A trip device is disclosed. The trip device according to an embodiment of the present disclosure comprises an adjustment crossbar. The adjustment crossbar is in contact with or is spaced apart from a shooter and can open or close a breaker having the trip device. The adjustment crossbar is formed by coupling a fixed crossbar and a movable crossbar. The movable crossbar is slidably coupled to the fixed crossbar. The shooter is in contact with the fixed crossbar. Therefore, regardless of the movement of the movable crossbar, the contact between the shooter and the fixed crossbar can be maintained.

A circuit breaker and method for operating a circuit breaker. The circuit breaker includes a first and a second breaker terminal, a bimetal stripe, a first conduction line, a switch with a first and a second contact, a triggering device mechanically coupling the bimetal stripe to the switch, a magnet and a detection device comprising a magnetic field sensor configured to detect a magnetic field of the magnet. The first conduction line is electrically coupled to the first breaker terminal and to the first contact and is wound around the bimetal stripe. The magnet is connected to at least one of the bimetal stripe, the triggering device and the switch.

A heater-bimetal apparatus is disclosed. The heater-bimetal apparatus has a heating element having a first portion and a second portion, a bimetal element coupled to the heating element at a third portion between the first and second portions, and a support member coupled to the heating element at the third portion, the support member including registration surfaces adapted to be received in pockets formed in spaced portions of circuit breaker housing. Assemblies including the heater-bimetal apparatus and methods of assembly of heater-bimetal assemblies are provided, as are other aspects.

Electromechanical circuit breakers are disclosed herein. In some embodiments, the breakers can be integrated into battery management systems to simplify battery management circuitry and/or to provide redundancy to the battery management systems. In some embodiments, the breakers can be provided to reduce damage to the battery management systems during hot-swapping of a battery cell. The breakers can be automatically resettable or not automatically resettable in various embodiments.

This disclosure relates to a heat sensitive electrical safety device with a manually resettable device and an automatically resettable fuse. The manually settable fuse prolongs the serviceable life of the automatically resettable fuse.

According to one embodiment, an electrical contact assembly is disclosed. The assembly includes a layer of a conducting metal, a layer of copper adjacent to the layer of conducting metal, and a face layer comprising silver graphite adjacent to the layer of copper.

A miniature safety switch is used in motor vehicle electronics. The miniature safety switch has a housing base, from which a fixed contact arm and a bimetallic contact arm, which has a moving contact and a bimetallic snap disk attached thereto, are led out. A PTC resistor is brought into direct contact with the bimetallic snap disk by a compression spring and is electrically integrated in such a way that, as a result of the heat generated by the PTC resistor, the bimetallic snap disk remains in the open position thereof in the event of triggering.
