Abstract: A ganged auxiliary switch for a circuit breaker comprises at least two auxiliary switches attached to each other in a side-by-side relationship so that they may be inserted into said circuit breaker as a single unit.

Abstract: A clip designed to retain a conductive strap to a circuit breaker case is disclosed. The clip comprises a main body portion and a flange. The main body portion includes a first edge and a second edge. The flange depends from the first edge of the main body portion and includes a first end and a second end. The first end of the flange is configured for attachment to the conductor strap and the second end of the flange and the main body portion configured to secure the conductor strap in mounting stability within the case and to prevent movement of the conductor strap relative to the case.

Abstract: An indicator on a stored energy motor operator indicates that the circuit breaker is “on” when the contacts are closed and the handle is in an on position and when the contacts are open and the handle is in an on position. The indicator only indicates that the circuit breaker is “off” when the contacts are open and the handle is in an off position. To achieve these conditions, the stored energy motor operator includes a flag bearing on and off indicia, the flag attached to one end of a connecting bar, the other end of the connecting bar pivotally connected within the stored energy motor operator. A lever is attached to a central portion of the connecting bar at a spring, the lever including a hook portion for hooking onto a pin within the motor operator. When the contacts are closed, thus indicating an “on” condition, the lever remains hooked onto the pin.

Abstract: A four-pole molded case circuit breaker is provided with connecting rods for simultaneously driving the contact arms in all four poles while at the same time allowing for a staggered contact depression in the fourth pole relative to the other three poles. A stabilizer clamp locks the connecting rods together to eliminate relative motion between the rods without interfering with the staggered contact depression. By staggering the contact depression in the fourth pole, a three-pole operating mechanism can effectively toggle a four-pole device since the load of the contact depression springs in all four poles is not seen by the operating mechanism at the same time.

Abstract: 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.
