Product Description
The Allen-Bradley 140G-JC0H3-D10 molded case circuit breaker, weighing 5.51 pounds, provides reliable electrical protection up to 250 Amps with a 100kA interrupting rating, electronic LSI protection, and a JC frame for efficient operation within a 100A range; its 1000V insulation voltage and 8kV impulse withstand voltage, combined with a mechanical life of 240 operations/hour and an electrical life of 120 operations/hour, make it ideal for ensuring electrical system safety and reliability in compact installations.
Is Your Device Showing These Signs?
The Allen Bradley 140G-JC0H3-D10 Molded Case Circuit Breaker commonly exhibits issues such as nuisance tripping due to incorrect overload settings or thermal magnetic calibration drift. Expect failures in the operating mechanism, preventing proper breaker actuation and requiring replacement of internal components. Contact erosion on the main contacts leads to increased resistance, overheating, and eventual failure, necessitating contact refurbishment or breaker replacement. Auxiliary contact malfunction is a frequent problem, disrupting remote monitoring and control circuits. Diagnose and address these issues promptly to maintain circuit protection and prevent downtime.
