Fuji Electric EA52AC BB2BEAC-040 Circuit Breaker

Fuji Electric EA52AC BB2BEAC-040 is a 40 Amp, two-pole, 240 V AC automatic circuit breaker engineered to interrupt current during overloads or short circuits and protect connected circuits, helping prevent damage to wiring and downstream equipment. As part of Fuji’s EA52AC family, the BB2BEAC-040 is designed to trip and disconnect both hot legs in a 240 VAC circuit, providing coordinated protection for feeders, motors, lighting runs, or other line-powered equipment housed in electrical panels and distribution boards. The BB2BEAC-040 designation identifies this specific 40 A, two-pole model within the EA52AC lineup, ensuring it matches Fuji Electric installations that require that exact part number and aligns with standard 240 VAC protection schemes. In typical electrical distribution setups, this device serves as a reliable form of overcurrent protection for 240 VAC circuits, with rapid fault interruption designed to minimize heat buildup, nuisance trips, and potential fire hazards in control panels. This particular part number, BB2BEAC-040, provides a precise fit for Fuji Electric systems that specify the EA52AC/BB2BEAC-040 configuration, making it the correct choice when a 40 A, two-pole 240 V circuit breaker is required.
