Rockwell 40G-G6C3-C50 125A MCCB

140G-G6C3-C50 Molded Case Circuit Breaker

This 140G-G6C3-C50 molded case circuit breaker is manufactured by Rockwell Automation. It features a 125A frame size, a rated current of 50 amps, and utilizes a thermal-magnetic trip unit. This breaker is designed to interrupt high fault currents, with a rating of 65kA at 480V and 70kA at 415V. It’s a three-pole device, meaning it controls three phases of power. A thermal-magnetic circuit breaker is composed of a breaker frame and a trip unit. The thermal element provides overload protection, while the magnetic element protects against short circuits.
