Description:TECHNICAL FIELD
[0001] The present disclosure relates, in general, to the rotary operated mechanism, and more specifically, relates to the mounting of the rotary handle on the molded case circuit breaker when a circuit breaker is in OFF condition.

BACKGROUND
[0002] Generally, the assembly of accessories particularly rotary operated mechanism with molded case circuit breaker in the correct state to prevent accidental damage and ensure user safety. The use of switching devices, conventionally known as switchgear, is well known for making, breaking, regulating and providing safety in a typical electrical distribution system. These devices are generally mounted inside a panel board for added safety of the operator. Most often these switching devices are operated from outside of the panel through the rotary-operated mechanism.
[0003] Rotary-operated mechanism (ROM) is installed in almost 90% of molded case circuit breaker (MCCB) panels. It works on the philosophy of rack and pinion arrangement. It consists of an enclosure with a rotary handle and gear train arrangement to drive the MCCB knob. The rotary handle is coupled with the driving gear which applies torque to the inside gear train arrangement and the gear train arrangement drives the pinion and rack. The MCCB knob goes into the rectangular slot given on the rack during installation of ROM on MCCB. The pinion engages with the rack and drives it by converting rotary motion to reciprocating and eventually drives the knob of the MCCB making it operable. During installation of ROM, the user has to ensure that the knob of MCCB should get intact in the slot of the rack. However, when the panel has a higher depth or due to many unavoidable situations, the user assembles the ROM in reverse orientation. Which gives a faulty indication of the contact state to the user and ROM parts also get damaged
[0004] Therefore, it is desired to overcome the drawbacks, shortcomings, and limitations associated with existing solutions, and develop a means that provides proper alignment of the ROM with the MCCB.

OBJECTS OF THE PRESENT DISCLOSURE
[0005] An object of the present disclosure relates, in general, to rotary operated mechanism, and more specifically, relates to the mounting of a rotary handle on molded case circuit breaker when the circuit breaker is in OFF condition.

[0028] FIG. 1A illustrates a simplified representation of ROM with MCCB after assembly, in accordance with an embodiment of the present disclosure.
[0029] In an embodiment, electrical distribution system 100 can include switching devices designed for making, breaking, and regulating electrical connections, as well as ensuring safety. These devices are typically housed within a panel board to enhance operator safety. In most cases, these switching devices are operated externally through a rotary-operated mechanism (ROM) 104. As depicted in FIG. 1A, the ROM 104, serving as an accessory for a molded case circuit breaker (MCCB) 102. The ROM 104 is configured to operate the MCCB 102 by a rotary handle 106 accommodated on the ROM 104.
[0030] FIG. 1B illustrates a simplified representation of ROM assembly with MCCB, in accordance with an embodiment of the present disclosure. The ROM 104 can include an enclosure 108 that encloses a driving gear 110, pinion 112 and rack 114. The enclosure 108 with the rotary handle 106 and gear train arrangement drive a knob 116 accommodated on the MCCB 102.
[0031] The rotary handle 106 coupled with the driving gear 110 imparts torque to an internal gear train arrangement, subsequently driving the pinion 112. The driving gear 110 receives the rotational force i.e., torque from the rotary handle 106 and transmits it to the internal gear train arrangement. The internal gear train arrangement transmits and modifies the torque received from the driving gear 110. The pinion 112 is a small gear connected to the internal gear train arrangement and configured to drive the rack 114 by converting rotary motion into reciprocating motion, thereby facilitating the movement of components within the ROM 104 and drive the knob 116 accommodated on the MCCB.
[0032] In an embodiment, a front cover 118 of the MCCB 102 is a protective element positioned at the front face of the MCCB 102 (also referred to as circuit breaker 102, herein). The front cover 118 is designed to enclose and safeguard internal components.
[0033] During installation of the ROM 104 on the MCCB 102, the knob 116 of the MCCB 102 goes into a rectangular slot of the rack 114 profile. During installation of the ROM 104, the user has to ensure that the knob 116 of the MCCB 102 should get intact in the slot of the rack. However, sometimes when the panel has a higher depth or due to many unavoidable situations, the user mounts the ROM 104 with MCCB 102 in reverse orientation, which leads to the malfunction of the unit or it may break the ROM internal mechanism. Also, it shows a false indication of the MCCB contact state on the ROM front facia.
[0034] To avoid the above limitation, the present disclosure is depicted in FIG. 2A to 2B and FIG. 3A to 3B respectively contributes to the overall assembly and functionality of the MCCB 102. The ROM 104 includes one or more inserts 202 (also referred to as inserts 202, herein) depicted in FIG. 2A is removably configured on the enclosure 108. Additionally, the front cover 118 of the MCCB 102 includes a first hole 204-1 and a second hole 204-2 shown in FIG. 2B configured to accommodate the inserts 202, respectively.
[0035] In a preferred embodiment, the front cover 118 is configured with at least a first hole 204-1 and a second hole 204-2. These holes are strategically positioned to allow for the insertion and secure placement of corresponding inserts 202 from the ROM 104. The correct alignment of the front cover 118 with the ROM 104 ensures proper orientation, facilitating the effective coupling of inserts 202 with designated holes, thereby contributing to the overall assembly and functionality of the MCCB 102. The proper alignment is configured for indicating precise contact state of the MCCB 102 on the ROM 104.
[0036] For instance, the ROM 104 is equipped with inserts 202 designed to fit into these holes. When the front cover 118 is correctly aligned with the ROM 104, the inserts 202 can be seamlessly inserted into the designated holes, ensuring a secure and precise fit. This proper alignment not only facilitates effective coupling but also contributes to the overall assembly and functionality of the MCCB 102. The specific configuration of proper alignment is crucial for indicating the precise contact state of the MCCB 102 on the ROM 104, enhancing the reliability and performance of the electrical distribution system.
[0037] FIG. 3A illustrates an exemplary simplified representation of the assembly of ROM on MCCB with correct orientation, in accordance with an embodiment of the present disclosure. FIG. 3A depicts an exemplary simplified representation demonstrating the assembly of the ROM 104 on the MCCB 102 with the correct orientation, as disclosed herein. The correct orientation facilitates the fixation or coupling of insert 202 to the first hole 204-1.
[0038] FIG. 3B illustrates an exemplary simplified representation of the assembly of ROM on MCCB with reverse orientation, in accordance with an embodiment of the present disclosure. FIG. 3B illustrates an exemplary simplified representation of the assembly of ROM on MCCB with the reverse orientation, as disclosed in an embodiment of the present disclosure. Assembly with the reverse orientation enables insert 202 to be fixed or coupled to the second hole 204-2.
[0039] Thus, the present invention overcomes the drawbacks, shortcomings, and limitations associated with existing solutions, and provides the system that introduces a modular design by incorporating one or more removable inserts on the ROM's enclosure. This modularity enables easy customization, facilitating adjustments to meet specific requirements or accommodate variations. Moreover, the system features a front cover on the MCCB with designated first and second holes, enhancing versatility during installation. The inclusion of these holes allows for the accommodation of one or more inserts, providing users with the flexibility to selectively install or remove inserts based on operational needs. Furthermore, the disclosed system ensures a robust connection by securely coupling the inserts with corresponding holes on the MCCB, a feature facilitated by the front cover. This secure coupling guarantees proper alignment of the ROM with the MCCB, promoting optimal performance and system longevity. In essence, the disclosed system combines modularity, versatility, and secure coupling mechanisms to offer a comprehensive solution for tailored and reliable electrical distribution applications.
[0040] It will be apparent to those skilled in the art that the system 100 of the disclosure may be provided using some or all of the mentioned features and components without departing from the scope of the present disclosure. While various embodiments of the present disclosure have been illustrated and described herein, it will be clear that the disclosure is not limited to these embodiments only.
