Square D FCL34070 – 70A 3 Pole Molded Case Circuit Breaker Bargain

Built for industrial networks, the Square D FCL34070 is a 70A, 3-pole current-limiting MCCB. It provides essential thermal-magnetic protection. Designed with a unit-mount configuration, this legacy F-frame breaker installs into Square D enclosures and switchboards. It is replaced by the HJL36070. The current-limiting capability restricts peak let-through current during short circuits, significantly reducing thermal stress on connected downstream equipment.
