140M-C2E-C16 | Allen-Bradley Motor Protection Circuit Breaker 10–16A

The 140M-C2E-C16 is a motor protection circuit breaker designed to protect motors and branch circuits from overloads and short circuits. It combines manual switching, thermal overload protection, and fixed magnetic short-circuit protection in one compact device. This makes it a suitable choice for compact control panel layouts where space and safety are both priorities. It ensures quick disconnection during high fault currents and helps minimize equipment damage. This breaker also simplifies coordination between protection devices in motor circuits.

At 400 Volts, the 140M-C2E-C16 has a short-circuit interrupt rating of 65 kiloamps. At 480 Volts, the maximum short-circuit rating is 30 kiloamps. These high interrupting capacities enable the breaker to be safely used in industrial environments with high fault currents. It meets the demands of motor feeders and group installations. These ratings ensure safe operation even in systems with powerful upstream transformers or generators.

The 140M-C2E-C16 measures 91 mm in height, 45 mm in width, and 54.9 mm in depth. Its compact size supports installation in densely populated control panels. The small footprint allows integration alongside contactors and overload relays without taking excessive space. Despite its small size, it maintains excellent thermal and short-circuit performance. These dimensions also conform to IEC modular panel layout standards.

Yes, the 140M-C2E-C16 is suitable for group motor installations. It supports short-circuit ratings of up to 30 kiloamps at both 480V and 600V for such applications. This allows multiple motors to be protected using a shared protection device. It helps simplify wiring and reduce component count in motor control panels. However, it is essential to follow installation guidelines to maintain coordinated protection

The 140M-C2E-C16 has been officially discontinued by Rockwell Automation as of February 25, 2022. It is no longer available for purchase as a new product and has been replaced under the engineering replacement category. The suggested replacement model is the 140MT-C3E-C16, which offers comparable motor protection functionality with updated features and improved compatibility. This new model adheres to modern standards and supports enhanced integration within newer control panel designs. Customers are encouraged to update their references and system designs to ensure continued support and maintain compliance.
