Terminal Types

Standard: Front-connected, pressure-wire terminals accepting copper or aluminum wire in sizes from 6 to 250 MCM. Back-connected and many special terminals are available. Consult factory.

Multi-Pole Trip Construction

Multi-pole breakers (2- and 3-pole) incorporate true common trip construction. When an overload condition occurs on any pole, the mechanism of that pole actuates an internal tripper bar which is connected to and operates all poles simultaneously. Thus an overload condition on any pole causes all poles to trip.
