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] Circuit breakers are generally used to protect any device from overload and short circuit. The circuit breakers comprise thermos-magnetic release that uses electromagnetic coils to provide short circuit protection, and bimetal to provide overload protection. The overload condition can be explained in simple terms as higher current (not as high as short circuit) persisting for long time. The system will be designed to carry a particular rated current for a period of time based on its duty cycle. If higher current (overload current) flows in the system for longer periods, then the system will not be able to dissipate the excess heat generated because of the overload and ultimately the system will break down.
[0004] During any fault, overload or short circuit, the thermo-magnetic release issues the break command and the circuit breaker trips to protect the connected device. After the fault is cleared the circuit breaker can be reset for normal operation. The whole operation of triggering the release involve angular toque that sometime causes a jerk to the release which is undesirable.
[0005] There is, therefore, a need for a triggering mechanism for a release, which is free from the above discussed problems.

[0038] As illustrated, a triggering mechanism for a release can include an overload shaft 102 having a plurality of extensions 104. A first bimetallic member 106 can be operatively configured with at least one extension of the plurality of extensions. The first bimetallic plate 106 can have a pre-defined shape to accommodate the at least one least one extension of the plurality of extensions. The pre-defined shape of the first bimetallic member 106 can be a U or C shape having a lower end 106-1 and an upper end 106-2. The at least one extension can be accommodated between two ends (106-1, 106-2) of the first bimetallic member 106. A second bimetallic member 108 can be configured on a heater 110 to sense a rise in temperature the release due to overload condition.
[0039] In an embodiment, a thermal screw 112 can be configured on the second bimetallic member 106, such that on sensing the rise in temperature in the release, the second bimetallic member 110 can bend to facilitate pushing a first extension 104-1, of the plurality of extensions 104.leading to a rotation of the overload shaft 102 in the first direction that can be a clockwise direction. Pushing the first extension 104-1 in a first direction can facilitate deforming the first bimetallic member 106.
[0040] In an embodiment, an actuating assembly can be operatively configured with the first bimetallic member 106 such that the deforming of the first bimetallic member 106 can facilitate triggering of the release. The actuating assembly can include a first member 114, having a first end 114-1 and a second end 114-2 configured at opposite side of the first member 114. The first member 114 can be operatively configured with the first bimetallic member 106.
[0041] In an embodiment, when the first extension 104-1 is pushed in the first direction (clockwise direction) the lower end 106-1 of the first bimetallic member can be pushed downwards and eventually the upper end 106-2 can also be pushed downwards. When the upped end 106-2 is pushed downwards, the first end 114-1 can be pushed a second direction (downwards) and the second end 114-2 can be pushed in a third direction (upwards) opposite to the second direction.

A triggering member 118 can be operatively configured with the second member 116 through a charged elastic member 120 such that the when second member is pushed in the third direction, the triggering member get released, by the energy of the charged elastic member 120, from the second member 116 for triggering the release.

A second magnet 124, having a free end 124-1 and an orthogonal member 124-2, can be pivotally coupled with the first magnet 122 such that there is a gap between the free end 124-1 and the first magnet 122. The free end 124-1 can get attracted towards the first magnet 122 in overcurrent condition. When the free end 124-1 gets attracted towards the first magnet 122, the orthogonal member 124-2 can get engaged with plurality of extensions 104 for rotating the overload shaft 102 in the first direction, which can facilitate triggering the release through the actuating assembly.
