Fuji Electric Co., Ltd. BU3EHC-015L Circuit Breaker

Fuji Electric BU3EHC-015L is an industrial, 3-pole circuit breaker rated for 15 A, with voltage ratings of 600 VAC and 250 VDC, designed to protect three-phase circuits by interrupting current during overloads or short circuits. When the current exceeds the set threshold, the device trips to halt power flow, helping prevent overheating and damage to wiring, devices, and downstream equipment. The three-pole arrangement ensures all three phases disconnect together, reducing the risk of partial shutdown and phase-to-phase faults. Typical use cases include protective interlock in industrial control panels and machinery where three-phase power distribution is essential and 15 A capacity is appropriate, with a 600 VAC or 250 VDC supply.
