Federal Pacific HFJ631070 Circuit Breaker, 70A, 3-Pole, 600V

Meet the Federal Pacific HFJ631070 circuit breaker—a purpose-built solution for demanding industrial electrical service, maintenance, and replacement projects. With a 70 A rating, a 3-pole design, and a 600 V operating capacity, this breaker is engineered to protect and simplify the most challenging three-phase applications.

Why this 3-pole, 70 A, 600 V breaker stands out

Designed for reliability in industrial environments, the HFJ631070 delivers robust short-circuit and overload protection across all three phases. This coordinated protection helps minimize motor wear, reduces downtime, and supports safer, more predictable equipment operation in manufacturing plants, processing facilities, and large commercial spaces. The three-pole configuration ensures simultaneous disconnection of each phase, preserving the balance of your system and preventing partial faults that can escalate issues.

• Three-pole protection ensures all phases trip together, maintaining system integrity during faults.
• 70 A rating provides meaningful protection for feeders and heavy-duty branch circuits powering motors, pumps, conveyors, and other industrial loads.
• 600 V maximum voltage aligns with typical industrial distribution, delivering dependable protection in standard three-phase environments.
• Part number HFJ631070 as your compatibility anchor—verify fit by part number and application requirements to confirm seamless replacement in your panel.
