An auxiliary switch actuating mechanism is for a circuit breaker including a housing, separable contacts, an operating mechanism with an operating handle interconnected to the separable contacts by a linkage assembly, and an auxiliary switch having a contact member. The auxiliary switch actuating mechanism includes an actuating lever with first and second ends and a pivot portion engaging the housing proximate the auxiliary switch. A torsion spring biases the actuating lever towards engaging and actuating the contact member of the auxiliary switch. The contact member is actuated when the separable contacts are not tripped open and the linkage assembly is not collapsed. When the circuit breaker trips, the linkage assembly collapses, engaging and pivoting the actuating lever, in order to overcome the bias and disengage and deactivate the contact member.

Reverse-action auxiliary switch actuator mechanism and circuit breaker employing the same

A circuit breaker includes a housing having an opening, separable contacts within the housing, and an operating mechanism for opening and closing the separable contacts. The operating mechanism includes a generally transparent operating handle having a portion protruding through the opening of the housing. An auxiliary switch associated with the operating mechanism provides a first normally closed output when the separable contacts are open and a second normally open output when the separable contacts are closed. A first LED indicator cooperates with the first output, is proximate the operating handle and is illuminated when the separable contacts are open. A second LED indicator cooperates with the second output, is proximate the operating handle and is illuminated when the separable contacts are closed. One of the first and second LED indicators illuminates the operating handle.

Circuit breaker employing an illuminated operating handle

A circuit breaker includes a housing, a pair of separable contacts within the housing, and an operating mechanism having an operating handle for opening and closing the separable contacts. A micro-switch cooperates with the operating handle and provides a first output when the separable contacts are open and a second output when the separable contacts are closed. A first LED indicator protrudes through the housing and cooperates the first output of the micro-switch. The first LED indicator is illuminated when the separable contacts are open. A second LED indicator protrudes through the housing and cooperates with the second output of the micro-switch. The second LED indicator is illuminated when the separable contacts are closed.

Circuit breaker empolying illuminating indicators for open and closed positions

A locking attachment is for a circuit breaker. The circuit breaker includes a housing enclosing separable contacts and an operating mechanism, an elongated operating member with a handle that operates to open and close the separable contacts, and an opening in the housing through which the elongated operating member protrudes. The opening has first and second ends corresponding to &ldquo;on&rdquo; and &ldquo;off&rdquo; circuit breaker positions, respectively. The locking attachment includes a locking member having a first end having a compressive segment with opposed portions for compressively capturing the operating member. The second end of the locking member is structured to engage the housing of the circuit breaker at one of the first and second ends of the opening in the housing, thereby locking the circuit breaker in either the &ldquo;on&rdquo; or &ldquo;off&rdquo; position.
