Deal Siemens / ITE CJ3B125 – 125A 3 Pole Molded Case Circuit Breaker

A drop-in replacement for aging commercial systems, the Siemens CJ3B125 provides 125A of reliable thermal-magnetic overcurrent protection. This 3-pole, 600VAC molded case circuit breaker features fixed long-time and instantaneous trip functions. The bolt-on design installs into classic ITE and Siemens switchboards, motor control centers, and CDP panelboards, bypassing the need for a CFD63B125 retrofit kit. Boasting a 100kAIC rating at 480VAC, its integral Amp-Trap limiters reduce fault stress.
