Federal Pacific Electric XJL631400 Circuit Breaker

The Federal Pacific Electric XJL631400 is a 400A, 3-pole circuit breaker intended for high-current 3-phase electrical systems and rated for operation up to 600 volts, combining conventional overcurrent protection with an XJL Fusematic shunt-trip accessory actuated by 125 VAC control signals. The XJL Fusematic shunt-trip in this model provides remote tripping capability, allowing a control circuit to initiate an instantaneous interruption in current for safety interlocks and emergency shutdown procedures in appropriate industrial and commercial installations. With its 3P configuration, the breaker protects three-phase feeders and equipment, making it suitable for protecting large motors, transformers, and other heavy-load circuits in power-distribution panels that require a 400 A rating. Rated for up to 600 V and designed for integration into compatible electrical assemblies, the XJL631400 serves as a robust solution when high-current, remote-trip-capable protection is required in environments where reliable, responsive circuit isolation is critical.
