| 144 | SHORTAGE VOLTAGE TRIP DEVICE OF MOLDED CASE CIRCUIT BREAKER | US13726373 | 2012-12-24 | US20130169387A1 | 2013-07-04 | Seung Jin HAM |
| Provided is a shortage voltage trip device of a molded case circuit breaker. In the molded case circuit breaker, driving current applied into a trip driving part is reduced in proportion to reduction of a power applied into a circuit. When the voltage applied into the circuit is greater than a rated voltage, the trip driving part is stopped, and an operation of a trip driving mechanism is restricted by a trip lever. When the voltage applied into the circuit is less than the rated voltage, the trip driving part is operated, and the restriction of the trip driving mechanism is released by the trip lever rotated by being linked with the operation of the trip driving part. Thus, the circuit may be more simply switched, and operation reliability of a product may be improved. Also, the product may have a more simplified structure. | ||||||
