INTERFACE FOR AUXILIARIES USED WITH PLUG-IN BASE

摘要

An interface for a plug-in circuit breaker for carrying auxiliary components is disclosed. The interface includes a substrate having a base surface secured to the circuit breaker and a mounting surface. A plurality of auxiliary contact blocks, each carrying eight auxiliary contacts, can be mounted on the mounting surface. A plurality of rating plugs, for avoiding insertion of a wrong breaker into a plug-in base, may further be mounted on the mounting surface. The interface may further include a plurality of tunnel-shaped passageways for routing auxiliary circuit wires and preventing their interference with moving parts of the breaker.
