  • Patent number: 6600396
    Abstract: 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.
