[0001] The present disclosure relates to low voltage draw-out Circuit Breakers and modules.

BACKGROUND
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art
[0003] Accessories of circuit breakers require separate power supply through secondary isolating contacts (SICs) to operate. Wires taken from the accessories are connected to the breaker SIC and power supply is connected to cradle SIC. In case of draw-out MCCBs, cradle SIC has to be removed and wiring has to be done or long wires have to be prewired to the SIC, which increases cost and risk to the user. Therefore, in existing mechanisms, wires are prewired in the cradle SIC 104, which increase the cost and force the user to have an additional terminal block to connect the wires. Furthermore, in existing draw-out type MCCBs, the SICs are in rear side and therefore access to the SIC is not possible when the breaker is inserted. Furthermore, in existing designs, one has to remove the SIC and do the termination, which has the chance of accidental damage to the product and to the user. Existing mechanisms therefore do not provide flexibility in SIC termination. Furthermore, prewiring and providing separate terminal block to SIC in existing mechanisms leads to additional cost and space in panel board.
[0004] There is therefore a need for a mechanism that avoids removal or pre wiring of SIC.

[0034] The present disclosure relates to a secondary isolating contact (SIC) holder of a SIC, wherein the holder avoids removal of the SIC during termination and eliminates prewiring of the SIC. In an aspect, the present disclosure relates a secondary isolating contact (SIC) holder of a SIC, wherein the SIC holder can include a holder rotating arm that is operatively coupled with a holder fixed arm, wherein the holder rotating arm is riveted to the SIC with a spacer to ensure free rotation of the SIC.
[0035] In an aspect, the holder rotating arm and the holder fixed arm can be connected to each other by a rivet. In another aspect, the holder is fixed to a side cover, wherein rotation of the SIC is arrested using a mounting screw. In yet another aspect, the holder can include two rotating hinges that allow rotation of the SIC in two axis.SIC can include two mounting holes, wherein one of the two mounting holes can be used as a rotating hinge, and second of the two mounting holes can be used for mounting the SIC to a cradle.
[0036] In an aspect, in order to terminate cradle SIC, mounting screw can be unscrewed, making the SIC flexible and rotatable, wherein the rotatable SIC can be supported on side cover to perform termination of the cradle SIC.
[0037] FIG. 1 illustrates an exemplary draw-out MCCB.
[0038] FIG. 2 illustrates an exemplary assembly of a SIC to a side cover.
[0039] FIG. 3 illustrates an exemplary SIC with a rotating holder in accordance with an embodiment of the present disclosure.
[0040] FIG. 4 illustrates an exemplary SIC with the mounting screw removed to allow free rotation of the SIC in accordance with an embodiment of the present disclosure.
[0041] FIG. 5 illustrates wiring being done after the SIC is rotated and placed using the side cover in accordance with an embodiment of the present disclosure.
[0042] FIG. 6 illustrates SIC being rotated back and fixed using mounting screw in accordance with an embodiment of the present disclosure.
[0043] With reference to FIGs. 1-6, in draw-out circuit breakers, accessories connected to the breaker SIC 102 and power supply is connected to cradle SIC 104, wherein during rack-in/out, the SICs get engaged and disengaged along with the circuit breaker. Draw-out MCCB has three positions connected, test, and disconnected, wherein the SIC has to make contact in test and connected condition. In this case, accessories are directly wired to the breaker SIC 102 but in cradle the SIC 104 has to be removed and wiring has to be done or long wires has to be prewired to the SIC. In order to avoid removal or pre wiring of SIC 104, rotatable type SIC 104 of the present disclosure ensures easy termination and safety of user. In this type, one has unscrew the SIC 104 then rotate and terminate the wires.
[0044] In an aspect of the present disclosure, SIC holder can include a holder rotating arm 110 and a holder fixed arm 112, both being connected by say a rivet 114. Holder rotating arm 110 can be riveted to the SIC with a spacer 116, which ensures free rotation of the SIC. Entire assembly can now be fixed to the side cover 106 as shown in FIG. 2, wherein rotation of the SIC can be arrested using the mounting screw 108.
[0045] According to one embodiment, SIC holder can have two rotating hinges, which allow to rotate in two axis,giving flexibility to the SIC. Two mounting holes can be made available in the SIC in which one can be used as a rotating hinge, and the other can be used for mounting the SIC to the cradle.For terminating the cradle SIC 104, one has to unscrew the mounting screw 108, which makes the SIC flexible,and then the user can rotate the cradle SIC 104 and support it on the side cover 106 of the draw-out to perform the termination of the cradle SIC 104 as shown in FIG. 4.
[0046] According to one embodiment, one exemplary purpose of the present disclosure is to avoid removal of the SIC during termination and eliminate prewiring of the SIC.In another aspect, the hinge can be in the holder clamps SIC in cradle,making it flexible to rotate in two axis for easy wiring.
[0047] The present disclosure further enables easy access of SIC termination and reduces the cost of pre wires and separate terminal block. Furthermore, the termination can be done to the SIC without removing it, and there is no need to use pre wires and terminal block for termination. In yet another aspect, the wires can be terminated to the breaker SIC 102 even after the breaker is put into the cradle. Furthermore, damage of the wires due to rack in/out can be avoided since the wires are in rear side of cradle SIC 104.
[0048] While the foregoing describes various embodiments of the invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof. The scope of the invention is determined by the claims that follow. The invention is not limited to the described embodiments, versions or examples, which are included to enable a person having ordinary skill in the art to make and use the invention when combined with information and knowledge available to the person having ordinary skill in the art.
