Westinghouse Cutler-Hammer FDB3015 Circuit Breaker

The Westinghouse Cutler-Hammer FDB3015 is a specialized three-pole molded case circuit breaker designed for robust protection in demanding industrial electrical environments. Rated for continuous operation up to 600VAC and 250VDC, this device handles high-load connections in main and sub-panel boards where reliable fault interruption is critical for personnel and equipment safety. It serves as a replacement component within older switchgear assemblies or new construction projects requiring adherence to established industrial standards for power distribution circuits. This unit maintains compatibility with various busbar configurations and mounting rails found in NEMA-rated enclosures commonly utilized across manufacturing plants and commercial facilities. Technicians integrate the breaker by confirming the specific load current aligns with the 15-ampere thermal magnetic trip settings before energizing the system.
