The sensing circuit (48, 50, 52) is configured to generate the sense signal representative of a power signal flowing through a power circuit (54, 56, 58). The control circuit (46) has a frame (74, 76) and is configured to receive the sense signal and to provide a trip signal on a first terminal (68). The actuator (42) is external to the control circuit frame (74, 76) and has a second terminal (98) coupleable to the first terminal (68). The actuator (42) is configured to receive the trip signal on the second terminal (98).

摘要： A signal accessory for a molded case circuit breaker, with the circuit breaker having an operating mechanism with a cradle pin, a cross bar and a trip bar and a main breaker cover. The signal accessory comprises a signal accessory mounting having a bottom mount and a top mount coupled to the bottom mount with the top mount configured to receive a switch and engage the breaker cover in an accessory socket. A switch member is rotably mounted on the bottom mount with the switch member having an actuator lever in contact with the operating mechanism of the circuit breaker and an actuator pad in contact with a switch mounted on the top mount. When the circuit breaker is opened or closed the operating mechanism moves a cross bar coupled to the contact arm. The cross bar moves the actuator lever of the switch changing the state of the switch.

摘要： An undervoltage release device for a circuit breaker is disclosed having an operating mechanism, a trip bar, line and load terminals, and a cover. The device includes a housing, a solenoid, upper and lower actuators aligned with a plunger of the solenoid and in selective contact with the trip bar, plunger and actuator reset levers mounted upon the solenoid frame, and pair of terminals in electrical contact with the solenoid coil and line terminals of the breaker, wherein the force of the solenoid corresponds to the line voltage. Also disclosed is a method for tripping a circuit breaker when line voltage drops below a selected value, in a circuit breaker having an operating mechanism and a trip unit with an intermediate latch. The method includes steps of closing the circuit breaker with the operating mechanism, installing the device in a cover of the circuit breaker, the device having a solenoid with a plunger and a plurality of actuators in selective contact with the plunger and the trip unit; and wiring the solenoid in parallel with the load circuit, wherein the magnetic force of the solenoid is proportional to the line voltage and maintains the plunger in contact with the actuators, and wherein the plunger is released by the solenoid when the line voltage drops below the selected value, thereby providing for at least one actuator to contact the trip unit and open the circuit breaker.
