Information About 140M-C2E-C16

The Allen-Bradley 140M-C2E-C16 circuit breaker is a 140M motor protection circuit breaker. It may be used for the following applications: disconnecting motor branch circuits, manual switching, overload protection (thermal protection) and short-circuit/branch-circuit protection (magnetic protection). The 140M-C2E-C16 circuit breaker is rated for 16 Amps of operating current. It supports normal break interrupting rating/breaking capacity. The 140M-C2E-C16 circuit breaker supports adjustable thermal and fixed magnetic protection. The motor current adjustment range is 10 to 16 Amps. The magnetic trip current rating is 208 Amps. The maximum short circuit current rating is 65 kiloamps at 400 Volts and 30 kiloamps at 480 Volts. The maximum Horsepower ratings for 3-phase operation are 5 Horsepower at 200 Volts, 5 Horsepower at 230 Volts, 10 Horsepower at 460 Volts, and 15 Horsepower at 575 Volts.

The maximum kilowatt output power ratings for the Allen-Bradley 140M-C2E-C16 circuit breaker are 4 kilowatts at 230 Volts, 7.5 kilowatts at 400/415 Volts, 10 kilowatts at 500 Volts, and 13 kilowatts at 690 Volts. When it is used as a motor protection breaker, the maximum fuse size for the 140M-C2E-C16 circuit breaker is 450 Amps, the maximum short circuit current ratings for group motor installation are 30 kiloamps at 480 Volts and 600 Volts, the maximum short circuit ratings are 30 kiloamps at 480 and 600 Volts for motor disconnect, and the maximum short circuit current rating is 30 kiloamps at 480 Volts and 277 Volts for the tap conductor protection. The height of the 140M-C2E-C16 circuit breaker is 91 millimeters, the width is 45 millimeters, and the depth is 54.9 millimeters.

Frequently Asked Questions about 140M-C2E-C16
Question: What is the primary function of the 140M-C2E-C16?
Date Update:12/06/2025
Answer:

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.

Question: What are the short-circuit ratings at different voltages?
Date Update:12/06/2025
Answer:

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.

Question: What are the mechanical dimensions?
Date Update:12/06/2025
Answer:

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.

Question: Is this circuit breaker suitable for group motor installation?
Date Update:12/06/2025
Answer:

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

Question: What is the lifecycle status of the 140M-C2E-C16 and what can replace it?
Date Update:12/06/2025
Answer:

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.
