Abstract
A linkage for a solenoid actuated circuit breaker operating mechanism is provided. The operating mechanism includes a trip device and a close device. Either the trip device or the close device is coupled to a solenoid, by an ultra-lightweight connection member. The ultra-lightweight connection member is so light as to not create a sufficient force to effect the trip device or the close device even when the circuit breaker is subjected to a shock load.

A linkage for a rotary solenoid actuated circuit breaker operating mechanism, said operating mechanism including a trip device and a close device, at least one of said trip device or close device coupled to at least one solenoid, said circuit breaker having at least one pair of separable contacts, said separable contacts actuated by said operating mechanism, and a control system structured to actuate said at least one solenoid, said linkage comprising an ultra-lightweight connection member extending between, and coupled to each, said rotary solenoid and at least one of said trip device or close device.
An operating mechanism for a circuit breaker, said circuit breaker having a control system and at least one pair of separable contacts, said separable contacts structured to move between a first, closed position, wherein said contacts are in electrical communication, and a second, open position, wherein said contacts are not in electrical communication, said operating mechanism comprising:
- a trip device coupled to said separable contacts and structured to move said separable contacts from said first position to said second position;
- a close device coupled to said separable contacts and structured to move said separable contacts from said second position to said first position;
- a trip solenoid coupled said control system and coupled to, and structured to actuate, said trip device by a first ultra-lightweight connection member;
- and
- a close solenoid coupled to said control system and coupled to, and structured to actuate, said close device by a second ultra-lightweight connection member.
A circuit breaker comprising:
- a control system and at least one pair of separable contacts, said separable contacts structured to move between a first, closed position, wherein said contacts are in electrical communication, and a second, open position, wherein said contacts are not in electrical communication;
- an operating mechanism having a trip device and a close device;
- a trip device coupled to said separable contacts and structured to move said separable contacts from said first position to said second position;
- a close device coupled to said separable contacts and structured to move said separable contacts from said second position to said first position;
- a trip solenoid coupled to said control system and coupled to, and structured to actuate, said trip device by a first ultra-lightweight connection member;
- and
- a close solenoid coupled to said control system and coupled to, and structured to actuate, said close device by a second ultra-lightweight connection member.
An operating mechanism for a circuit breaker, said circuit breaker having a control system and at least one pair of separable contacts, said separable contacts structured to move between a first, closed position, wherein said contacts are in electrical communication, and a second, open position, wherein said contacts are not in electrical communication, said operating mechanism comprising:
- a trip device coupled to said separable contacts and structured to move said separable contacts from said first position to said second position;
- a close device coupled to said separable contacts and structured to move said separable contacts from said second position to said first position;
- a trip solenoid coupled to said control system and coupled to, and structured to actuate, said trip device by a first relatively massless connection member;
- and
- a close solenoid coupled to said control system and coupled to, and structured to actuate, said close device by a second relatively massless connection member.
