HFB3070L - 70Amp Circuit Breaker

HFB3070L - 70Amp Circuit Breaker

The HFB3070L is a 70 Amp, 3-pole thermal-magnetic molded case circuit breaker designed for use in compatible HFB-series electrical distribution systems. Equipped with a non-interchangeable trip unit, this breaker provides dependable protection against overloads and short circuits while maintaining the factory-configured trip characteristics required for compatible equipment. When you're replacing an existing breaker, matching the original unit's amperage, voltage rating, interrupting capacity, pole configuration, trip characteristics, terminal style, and physical dimensions is essential for proper form, fit, and function.
