ABSTRACT:
Opening electrical contacts or electrical circuit interrupters. Particularly, a design for an electrical switch having opening electrical contacts which inhibit arcing. More particularly, a circuit breaker having a micro-contact interface comprising a contact with a plurality of contact points capable of handling high steady state currents conventionally handled by small to medium size molded case circuit breakers (i.e., 0.5 A.sub.rms to 400 A.sub.rms) at distribution voltage levels (120 V.sub.rms to 600 V.sub.rms).
