OMRON J7MN-3R-2E5 Manual Motor Starter

The OMRON J7MN-3R-2E5 (J7MN-3R-2E5) is a manual motor starter and circuit breaker designed to protect motor branch circuits against short circuits, overloads, and phase failures in industrial automation panels. Built as part of the OMRON J7MN series, this protective switching device integrates manual switching, thermal overload disconnection, and magnetic short-circuit tripping capabilities into a compact DIN-rail mountable enclosure. It serves as an essential motor control component for protecting electric motors, pumps, conveyors, fans, and compressors across manufacturing environments and motor control centers. Engineered for seamless integration alongside contactors and overload relays, the unit provides manual control through its front-facing rotary operating mechanism while isolating downstream equipment during maintenance procedures. Its robust industrial design ensures dependable line protection and current interruption under challenging operating conditions. With its standardized mounting footprint, the J7MN-3R-2E5 simplifies cabinet assembly, wiring, and routine operational inspection in both new installations and retrofitted automation machinery.
