Westinghouse HFA3110 is a molded case circuit breaker designed for providing reliable overcurrent protection in three-phase industrial electrical systems. It features a 110A continuous current rating and a 600V AC voltage rating, with a 25kA interrupting capacity at 480V AC to safely clear high-level faults. The three-pole, bolt-on thermal-magnetic breaker utilizes a long-time and instantaneous (LI) trip function for coordinated protection against both overloads and short circuits. Its robust construction complies with relevant industry standards for safety and performance, making it suitable for integration into motor control centers, industrial panels, and power distribution equipment.
