摘要： A magnetic trip mechanism is provided for an electrical switching apparatus. The magnetic trip mechanism includes a magnetic member, an armature having opposing first and second ends and first and second sides, an armature restraint and a biasing element. The armature moves among first and second positions corresponding to separable contacts of the electrical switching apparatus being tripped open and closeable, respectively. The armature restraint includes first and second portions. In the first position, the first side of the armature engages the magnetic member. In the second position, the second side of the armature engages the second portion of the armature restraint. The armature restraint and the biasing element comprise a sub-assembly, which is removably coupled to the magnetic member. After being removably coupled to the magnetic member, the biasing element is chargeable to bias the armature away from the first position toward the second position.

摘要： 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.

摘要： 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.

摘要： 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 “on” and “off” 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 “on” or “off” position.

摘要： A gas deflector for a line-in connector of a circuit breaker. The gas deflector is coupled to a collar with a top and a cavity, a threaded opening through the top, a screw threaded in the threaded opening. The collar is attached to the line-in for the circuit breaker. The gas deflector is an L-shaped shield with an integral screw sleeve and a slot sized to allow a terminal strap to pass therethrough. The terminal strap is connected to the collar. The shield device covers the collar top and the cavity and is held in place by the screw passing through the sleeve and by the terminal strap passing through the slot. The shield substantially reduces the amount of ionized gas infiltrating into the collar.

摘要： A push-to-trip assembly is provided for an electrical switching apparatus, such as a circuit breaker. The push-to-trip assembly includes a push-to-trip actuator having first and second ends and being movable among a first position corresponding to the circuit breaker separable contacts being closeable, and a second position corresponding to the second end cooperating with a trip bar to cause the circuit breaker operating mechanism to trip open the separable contacts. The first end is accessible from the exterior of the housing to actuate the push-to-trip actuator from the first position to the second position. A biasing element biases the push-to-trip actuator away from the base toward the first position. At least one cover stop of the push-to-trip actuator engages a corresponding portion of the housing cover to stop movement of the push-to-trip actuator. An overtravel restraint proximate the second end of the push-to-trip actuator restrains movement of the trip bar.

摘要： An improved paralleled multiple pole circuit breaker employs a conductive element of known resistance connected in series within each pole. A bridging conductor electrically connects together the poles and balances the current flow therethrough at a location between the sets of separable contacts and the conductive element of each pole. The conductive elements are mass-produced plate-like blades of a material having a resistance that is substantially fixed and is substantially independent of temperature. During operation, the voltage drop across one of the conductive elements can be determined by directly measuring the voltage drop between the ends of the conductive element without additionally interposing copper, solder, or other materials between the locations on the conductive element across which the voltage drop is determined.

摘要： 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.

摘要： A movable arm assembly is for an electrical switching apparatus including a stationary contact and an operating mechanism. The arm assembly includes a biasing member and an arm member having a first end, an opposite second end, a pivot point therebetween, and a portion having a longitudinal axis. A movable contact is disposed at or about the first end. The arm member engages a crossbar member at or about the pivot point such that the arm member can pivot from a first position to a second position. The biasing member engages the arm member at a point between the pivot point and the second end and includes a portion that engages and biases against a housings of the crossbar member. The longitudinal axis of the portion of the arm member is oriented generally parallel to the portion of the biasing member when the arm member is at the first position.
