International Classification:

H01H 6702

US Classification:

335132, 335 17, 335202

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.

International Classification:

H01H 71/24
H01H 71/02

Abstract:

A shunt trip device for a circuit breaker having a trip bar for tripping the circuit breaker. The device includes a housing having a slot and a bottom wall having a pivot pocket. The device also includes a lever arm having a lever projection portion and a pivot portion. The pivot portion is located in the pivot pocket to enable rotation of the lever arm in the slot about a lever rotation axis between first and second positions. When the lever arm is in the second position, the lever projection portion moves the trip bar and trips the circuit breaker. The device further includes an actuation device that moves the lever arm to the second position. The pivot portion and pivot pocket form a configuration that increases a perpendicular distance between a force generated by the actuation device and the lever rotation axis.

International Classification:

H01H 21/22

Abstract:

An accessory device for a circuit breaker. The device includes a housing having a top wall and a hinge portion. The device also includes a plunger arm that extends from the hinge portion to form a cantilever wherein the plunger arm includes a first surface and a sloped surface. The plunger arm is moveable between an initial position wherein the plunger arm does not activate the first and second switches located in the housing and a deflected position wherein the first and sloped surfaces simultaneously contact the first and second switches, respectively, thereby activating the first and second switches. The plunger arm also includes a plunger portion that is oriented transverse to the plunger arm. A mating surface is formed on the plunger portion that mates with a mating surface of a circuit breaker operating mechanism. Further, the housing, hinge portion, plunger arm, and plunger portion are integrally formed.
