Product Description
The Allen-Bradley 140G-H6C3-C70 is a 70-Amp, 3-pole molded case circuit breaker from the 140G family, offering thermal/magnetic protection and various mounting options. This H-frame breaker, weighing 1.2 kg and measuring 90 x 82.5 x 130 mm, requires disconnection of power before installation or maintenance and housing in a protective enclosure. It features a non-adjustable thermal trip at 70 Amps and a magnetic trip at 700 Amps. Optimal performance is achieved below 40C, with derating above this temperature. Its electrical life is rated at 8000 operations at 415 VAC and 120 operations/hour, while its mechanical life is 25,000 operations at 240 operations/hour. The breaker's rated insulation voltage is 1 kV and its rated impulse withstand voltage is 8 kV, according to IEC standards.
Is Your Device Showing These Signs?
The Allen Bradley 140G-H6C3-C70 Molded Case Circuit Breaker commonly experiences issues such as nuisance tripping due to incorrect overload settings or thermal magnetic calibration drift. Contact erosion and pitting on the breaker's contacts are frequent problems, leading to increased resistance and potential failure. The operating mechanism can become stiff or inoperable due to accumulated debris or corrosion, hindering proper breaker function. Inspect the breaker's insulation resistance, as degradation leads to ground faults. Replace damaged or worn internal components to restore optimal performance and prevent catastrophic failures.
Technical specifications
The Allen-Bradley 140G-H6C3-C70 is a 70-Amp, 3-pole circuit breaker providing thermal/magnetic protection. This H-frame breaker requires safety precautions during installation and maintenance, including power disconnection and enclosure housing. It has fixed thermal (70A) and magnetic (700A) trip settings, performs best below 40C, and has specified electrical and mechanical life expectancies. It also meets IEC standards for insulation and impulse withstand voltage.
Our Repair Process for the
140G-H6C3-C70
Our repair process for the Allen Bradley 140G-H6C3-C70 Molded Case Circuit Breaker begins with a thorough inspection to identify issues such as nuisance tripping, contact erosion, and operating mechanism stiffness. Overload settings are verified and recalibrated to eliminate incorrect tripping. Contact surfaces are cleaned and reconditioned to reduce resistance, and severely damaged contacts are replaced. The operating mechanism is disassembled, cleaned, lubricated, and adjusted to ensure smooth and reliable function. Insulation resistance is tested, and any degraded insulation is addressed. All damaged or worn internal components are replaced with new, high-quality parts to restore the breaker to optimal performance and prevent future failures.
