Heavy-Duty Three-Pole High Performance – Three-phase protection of circuits from 50 to 100 amperes.
Interphase Insulation – Insulating interphase barriers separate adjacent terminals.
Common Trip Bar – One bar connects the three operating mechanisms for simultaneous trip action. Trip bar is removable for installation.
Performance Rated Circuit Breaker – The 940 series is the only three pole heavy-duty aircraft-type circuit breaker available in the 50 to 100 ampere range and consists of three specially built 160-012 breakers with insulating interphase barriers separating adjacent terminals. The unit has a common trip bar connecting the three operating mechanisms so that an overload tripping one pole will simultaneously trip the remaining two poles.
