Multi-mode of operation tripper for molded case circuit breaker

The utility model relates to a multi-operation-mode release for a molded case circuit breaker. The multi-operation-mode release comprises a first shell (10), a release wiring part (20) and a second shell (30). And a release circuit board (40), a release actuating mechanism (70), a release push rod limiting mechanism (50) and a release alarm mechanism (60) are arranged in the second shell (30). The multi-operation-mode release has a first operation mode used for protecting the circuit breaker in the power-on overvoltage and overcurrent states, a second operation mode used for protecting the circuit breaker in the power-on closing state and a third operation mode used for preventing misoperation of the release in the non-power-on state. 本实用新型涉及一种用于塑壳断路器的多操作模式脱扣器，其包括第一壳体(10)、脱扣器接线部(20)和第二壳体(30)。在所述第二壳体(30)内布设了脱扣器线路板(40)、脱扣器致动机构(70)、脱扣推杆限位机构(50)以及脱扣器报警机构(60)。所述多操作模式脱扣器具有用于断路器在通电过电压和过电流状态保护的第一操作模式、用于断路器在通电合闸状态的第二操作模式以及用于脱扣器在未通电状态防止误操作的第三操作模式。
