HFB3040 - 40Amp Circuit Breaker

HFB3040 - 40Amp Circuit Breaker

The HFB3040 is a 40 Amp, 3-pole thermal-magnetic molded case circuit breaker designed for use in compatible HFB-series electrical distribution systems. Featuring a non-interchangeable trip unit, it provides dependable protection against overloads and short circuits while preserving the factory-configured trip characteristics required for the original equipment. When maintaining or servicing existing electrical systems, matching the original breaker's amperage, voltage, interrupting capacity, pole configuration, and physical dimensions is essential for proper fit and function.
