Product Description
The Allen-Bradley 140G-G2C3-C15 is a 125 Amp, 3-pole thermal-magnetic circuit breaker from the 140G family, designed for short-circuit protection in control panels and sized according to NEC Table 430-152. Suitable for 600VAC (690VAC IEC) branch or main circuits, it has a 25kA breaking capacity at 480VAC and features a fixed thermal/magnetic trip unit with 500A thermal and 15A magnetic trip ratings for instantaneous tripping upon overcurrent. Protection is provided by both a bimetallic element for thermal overload and an electromagnet for magnetic short circuits. It's rated for 25,000 mechanical operations (240/hour) and 8,000 electrical operations (120/hour), includes standard pigtail wiring for internal accessories, mounts on a DIN rail, and offers IP20 or IP40 ingress protection. Calibrated for 40C ambient temperature with a storage range of -40 to 80C, it weighs 1.1 kg and measures 76 x 70 x 130 mm.
Is Your Device Showing These Signs?
The Allen Bradley 140G-G2C3-C15 Molded Case Circuit Breaker commonly experiences issues such as nuisance tripping due to incorrect overload settings or thermal magnetic trip unit malfunction. Contact wear and degradation on the line and load side connections cause increased resistance and potential overheating. The operating mechanism can become stiff or fail, preventing proper breaker operation and requiring replacement. Calibration drift in the trip unit necessitates recalibration or replacement to ensure accurate fault protection. Inspect the breaker for physical damage, including cracks or deformation, which compromise its integrity and require immediate attention.

Our Repair Process for the
140G-G2C3-C15
Our repair process for the Allen Bradley 140G-G2C3-C15 Molded Case Circuit Breaker begins with a thorough visual inspection for physical damage, such as cracks or deformation. We then assess the line and load side connections for wear and degradation, addressing any increased resistance or potential overheating issues. The operating mechanism is inspected for stiffness or failure, and replacement occurs if necessary. We evaluate the thermal magnetic trip unit for malfunction and address nuisance tripping issues by correcting overload settings. Calibration drift is assessed, and the trip unit is recalibrated or replaced to guarantee accurate fault protection.
