Siemens / ITE CF3B070 – 70A 3 Pole Molded Case Circuit Breaker Hot Picks

Providing advanced short-circuit defense, the Siemens CF3B070 is a 3-pole, 70A current-limiting molded case circuit breaker. It utilizes thermal-magnetic trip technology and delivers a 200kAIC interrupting capacity at 480VAC. This bolt-on MCCB mounts into compatible Siemens switchboards and motor control centers. It serves as an exact legacy replacement for older C-Frame breakers, while the CED63B070 is its modern substitute. Built-in Amp-Trap fuses actively restrict let-through energy.
