Product Description
The Eaton Cutler-Hammer Allen-Bradley 140G-K6H3-D40 is a 3-pole molded case circuit breaker with a K frame, designed for industrial applications. It offers 400 Amp current rating at 40C, a 65kA interrupting rating, 8kV impulse withstand voltage, and 1000V insulation voltage, with a nominal operating voltage of 690VAC. Featuring an Electronic LSI trip unit for comprehensive protection and weighing approximately 7.17 pounds, this breaker provides thermal, magnetic, and electronic trip protection with high interrupting capabilities. Part of the 140G series, it offers a range of interruption ratings (25-200kA) and current ratings (16-3000A) across the series, space-saving dimensions, global approvals, various mounting options, and supports common accessories for ease of use, making it suitable for control panel line protection.
Is Your Device Showing These Signs?
The Allen Bradley 140G-K6H3-D40 Molded Case Circuit Breaker commonly experiences issues such as nuisance tripping due to incorrect overload settings or thermal magnetic calibration drift. We address failures in the operating mechanism, preventing proper breaker actuation and reset. Terminal damage from improper torque during installation or repeated cycling causes connection failures. Arc chutes degrade over time, reducing the breaker's interrupting capacity and requiring replacement. We resolve communication faults within the breaker's internal monitoring system, ensuring accurate data reporting.
