An operating handle assembly is provided having an improved handle engagement arrangement, thereby enabling the operating handle assembly to be adaptable for both human and machine interaction without the requirement of special attachment hardware. An operating handle assembly having a handle base and handle stem can accept a first handle extension suitable for human interaction or a second handle extension suitable for machine interaction. Assembly features provide for proper assembly of the handle extension to the handle stem while maintaining appropriate electrical clearances to live parts. The two part operating handle assembly, handle base with handle stem plus handle extension, provides for improved manufacturability of the host device, whereby the end-use construction of the host device need not be identified until a late point in the production cycle. The host device may be, but is not limited to, a standard circuit breaker, a rotary circuit breaker, a switch, or a disconnect device.

An auxiliary position switch assembly for a circuit breaker provides an electrical signal to an external monitoring device indicative of the position of a pair of separable contacts of the circuit breaker. The auxiliary position switch assembly engages a rod that switches from a retracted and extended position in response to the opening and closing of the separable contacts of the circuit breaker. The switch assembly includes a switch having a pair of separable contacts and a plunger having one end engaging one of the contacts. The plunger slidably engages a concave upper engagement surface of a pivotally mounted actuator. The actuator includes a lower convex engagement surface that engages the rod. A biasing spring connected to the actuator urges the actuator against the rod during operation of the switch assembly. The switch provides a normally-open output or a normally closed-output depending upon the position of the plunger on the upper surface of the actuator for a specific position of the separable contacts of the circuit breaker.

An industrial-rated circuit breaker line and load terminal lug and connector for connection with the power distribution line and load cables also includes a receptacle that allows connection with an auxiliary device for load indication and voltage metering. The receptacle is in the form of an insulative sleeve arranged around a metal contact blade in electric circuit with the line and load lugs. Electrical connection with the line and load cables and the auxiliary device occurs when the combined terminal lug and connectors are connected with the power distribution line and load cables.

This invention relates to a high ampere-rated circuit breaker which meets the electrical code requirements of the world market. The charging of the powerful operating springs controlling the circuit breaker contacts is made manually by means of a ratchet and pawl assembly. A two stage latching arrangement controls the retention and release of the pawl to retain and discharge the operating springs.

A molded case circuit breaker of the type containing an electronic trip unit to control an operating mechanism for automatically turning the circuit breaker contacts between ON and OFF conditions under overload conditions and a handle operator for same under quiescent conditions is designed for operation with a motor operator unit. The operating mechanism unit is structured to resist the high impact forces translated to the mechanism by the motor operator unit.

This invention relates to a high ampere-rated circuit breaker which meets the electrical code requirements of the world market. The charging of the powerful operating springs controlling the circuit breaker contacts is made manually by a ratchet and pawl assembly. A logic plate interacts with the operating springs charging gear and a logic lever interacts with the ratchet and pawl assembly to prevent the charge indicating flag from signaling until the operating springs have become fully charged.

A molded case circuit breaker enclosure and operating components are provided with additional features to enable compliance with a variety of international electrical requirements for sales in the world market. The circuit breaker operating handle is prevented from returning to the OFF position upon contact welding as one example. Another modification includes a reinforcement and rejection pin used with the enclosure case. A further modification includes a shield used with the movable contact arm to prevent the arc gas contaminants from contacting the circuit breaker operating springs.

This invention relates to a high ampere-rated circuit breaker which meets the electrical code requirements of the world market. The charging of the powerful operating springs controlling the circuit breaker contacts is made automatically by means of an electric motor. The circuit breaker operating handle connects with the operating springs through a motor operator interface unit to allow manual charging of the operating springs upon stalling of the electric motor.

The contact depression effected between the fixed and moveable contacts in a high ampere-rated circuit breaker is fixed after assembly of the current carrying components by the provision of a multi-dimensional contact carrier support bearing. The selection of the support bearing dimension fixes the height of the movable contact arm and the attached movable contact relative to the subjacent fixed contact. Control of the contact depression improves circuit interruption efficiency and extends the operating life of the circuit breaker contacts.
