Industrial FW3040L Three Phase Circuit Breaker

The Cutler Hammer FW3040L functions as a robust three-pole molded case circuit breaker engineered specifically for industrial three-phase electrical distribution systems rated at nominal voltages up to 600 volts AC. With a certified continuous ampere rating of 40 amperes equipped with thermal magnetic trip units, this component serves as the primary protection device safeguarding downstream wiring and connected loads from dangerous overcurrent conditions caused by short circuits or sustained overloads. Designed to mount securely via bolted connections onto standard busbars, these breakers integrate seamlessly into commercial and industrial panelboard assemblies located in facilities managing heavy machinery, HVAC systems, and large-scale lighting arrays. Adherence to rigorous National Electrical Code specifications ensures that installing this unit complies with safety regulations governing low-voltage branch circuits, providing necessary disconnecting means and reliable interruption capacity for maintenance teams working on powered equipment.
