Allen-Bradley 140M-C2E-C20 3-Pole Manual Motor Protection Circuit Breaker, 14.5–20A Adjustable Thermal Trip

Allen-Bradley 140M-C2E-C20 3-Pole Motor Protection Circuit Breaker for 14.5–20A Motors

The Allen-Bradley 140M-C2E-C20 is a manual motor protection circuit breaker engineered to provide coordinated overload and short-circuit protection for three-phase motor loads. Built on a 32-amp Frame C platform, it is factory configured with an adjustable thermal current range of 14.5 to 20 amps for precise motor protection.

Integrated Thermal and Magnetic Motor Protection

• Adjustable thermal overload protection with Trip Class 10 response
• Fixed magnetic short-circuit protection calibrated at 13× rated current
• Three-pole design for balanced three-phase motor circuits
• Rotary handle with clear ON, OFF, and TRIP status indication

IEC-Rated Frame C Architecture

Designed for IEC motor control systems, the 140M-C2E-C20 supports operating voltages up to 690 VAC and mounts directly onto standard 35 mm DIN rail. Its compact frame allows seamless integration into motor control panels while maintaining compliance with global electrical standards.

Typical Applications

• Three-phase motor branch circuit protection
• Type F combination motor controllers with Allen-Bradley 100-C contactors
• Industrial automation and motor control panels
