Abstract: A low resistance current interrupter for detecting the occurrence of an unsafe condition and terminating power to an electrical circuit. The current interrupter comprises two in-line connectors having a gap formed therebetween. An electrically conductive pin is disposed in the gap for movement between a first, extended position, wherein the pin bridges the gap to establish electrical contact between the connectors, to a second, retracted position wherein electrical contact is broken. The device further includes means for sensing the occurrence of an unsafe condition and generating a signal indicative thereof, and an electromechanical means such as a solenoid which, upon receiving said electrical signal, is activated and causes the pin to move to the second position.

Abstract: A low insertion force, high current connector terminal for vehicular applications. The terminal includes a receptacle connector member having means for varying the inside diameter of a socket thereof, and a pin connector member insertable therein. The receptacle connector member includes an outboardly displaceable resilient finger having a first stop surface engageable with a second stop surface formed on the pin connector member to prevent accidental axial displacement of the two connector members. A slot and mating guide are disposed on, respectively, the receptacle connector member and the pin connector member, said slot and guide serving as both a guide means when the members are connected and also as an indexing means to prevent the connection of two non-mating connector members.

Abstract: A circuit breaker characterized by its ability to qualify for controlling high electrical capacity in a concise configuration employing two sets of contacts separated by a dielectric barrier having anti-arcing features to minimize arcing in a minimal size circuit breaker. Control of the contact movement is through a pivoted actuator and over-center linkage in conjunction with a bell crank lever operating a spring mounted contact moving through a short radius.

Abstract: A circuit breaker having two subassemblies, connected via snap-lock means, which mesh together to provide manual operation with "trip free" response to overloads and no latch load on the bimetallic element.

Abstract: A back lighted trip indicator for a circuit breaker comprising an opaque tubular shield and a light translucent prism telescopically received in the shield and movable from a position totally within said shield when the manual operator is in the "ON" position to an exposed condition when the manual operator moves to the "OFF" position thereby to reflect ambient light through a frontal face on the prism to back light indicia on the frontal face of the prism.

Abstract: The disclosure relates to a bushing that can be interlocked with an electrical circuit protector without modification thereof to provide for snap-in mounting of the protector in a panel.

Abstract: The disclosure relates to an electrical circuit breaker comprising a housing having a pair of external terminals for connection to a source of electrical current. Current responsive means is supported internally of the housing and electrically connected to said terminals and to separable internal contacts. Current flow through said current responsive means effects separation of said contacts upon the occurrence of a predetermined electrical condition. A fusible element disposed externally of said housing is electrically connected in series with said contacts and current responsive means and is operable to effect interruption of the electrical circuit through said circuit breaker upon failure of said current responsive means to respond to said predetermined electrical condition.
