HFB3050L - 50Amp Circuit Breaker

HFB3050L - 50Amp Circuit Breaker

The HFB3050L is a 50 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, it provides dependable protection against overloads and short circuits while preserving the factory-configured trip characteristics required for compatible installations. When you're maintaining existing electrical systems, matching the original breaker's amperage, pole configuration, voltage rating, interrupting capacity, trip characteristics, and physical dimensions is essential for proper fit and function.
