Cutler-Hammer CA3150X U Molded Case Circuit Breaker

Cutler-Hammer CA3150X U molded case circuit breaker is a 150-amp, 3-pole device rated for 240V, designed to provide overcurrent protection in electrical distribution panels and power systems. As a molded case circuit breaker, it interrupts fault or overload currents to safeguard wiring and equipment. The 150 A, 3P, 240 V rating defines the size and range of circuits it can protect, making it suitable for feeders and distribution circuits in three-phase power systems. This Cutler-Hammer device is intended for use in standard electrical assemblies that accommodate molded case breakers of this class, offering reliable protection in commercial and light industrial installations. In practice, CA3150X U units help isolate circuits when abnormal current levels are detected, supporting safe operation and minimizing downtime.
