Industrial MCB1-4D-3P-D32 Miniature Circuit Breaker

The Fmx MCB1-4D-3P-D32 is a three-pole miniature circuit breaker (MCB) built for industrial electrical distribution. It is rated for 32 A and supports up to 480 V AC, making it suitable for protecting three-phase circuits in commercial or industrial panels against overloads and short circuits. As a protective device, it interrupts current automatically when fault conditions are detected, helping prevent wiring damage and equipment failures. The model designation MCB1-4D-3P-D32 identifies a 3-pole, 32-amp, 480-volt AC breaker from the Fmx family. Use this unit in distribution layouts that require compact, modular protection for three-phase circuits, ensuring safe disconnection during abnormal conditions while fitting standard panelboard configurations.
