Product Description
Product Overview
The Allen-Bradley 140-CMN-6300 is a Motor Protection Circuit Breaker designed to provide thermal overload and magnetic short-circuit protection for three-phase motors. Compact and modular, it fits directly into control panels and motor control centers (MCCs), making it ideal for industrial manufacturing, pumps, conveyors, and compressors.
Functional Description
The 140-CMN-6300 protects motors from overload, short circuits, and phase faults while enabling safe manual switching. Its dual protection mechanism—thermal and magnetic—ensures rapid response to abnormal conditions. The breaker supports a wide voltage range (230–690 VAC) and a trip range of 40–63 A, providing flexibility for global applications.
