Abstract: A connector module for overcurrent protection devices uses a printed circuit board substrate as a support surface for line and load busbar members and auxiliary signal clip connectors disposed on one side of the substrate. Passageways in the substrate enable male current plugs to extend through the substrate to mate with sockets disposed in the busbars. Additional passageways enable auxiliary contact terminals to extend through the substrate. Clip connectors disposed on the substrate are used to make electrical contact to the auxiliary terminals. In a preferred embodiment, the sockets and clips are shaped and dimensioned to mate with the current and alarm contact terminals of a plug-in circuit breaker.

Abstract: An insulation displacement connector is provided that has two housings. The first housing encloses surge protection. Terminals extend from the first housing. The second housing has insulation displacement terminals with first ends for connection with insulated wires and with second ends for connection to the terminals extending from the first housing. The two housings are to be joined together to complete an electrical line from one insulation displacement terminal to the other via the surge protection. Thus, surge protection is in one sub assembly protected from the environment, and the insulation displacement terminals are in another subassembly protected from the environment. The housings have a detent assembled condition enabling relative positional adjustment before joining of the housings. Electrical testing for the line circuit and for the surge protection may be performed upon the closed assembly.
