Description
Allen-Bradley 140M-C2E-B16 Motor Protection Circuit Breaker
The Allen-Bradley 140M-C2E-B16 serves as the primary 140M-C2E Motor Protection Circuit Breaker utilized to execute thermal overload interruption and magnetic short-circuit isolation across Bulletin 140M motor feeder platforms. The unit supports adjustable thermal protection from 1.0-1.6 A with fixed magnetic trip functionality for low-power three-phase motor circuits.

Deterministic Protection Coordination
The Bulletin 140M platform is deployed within Allen-Bradley motor control architectures interfacing with EtherNet/IP and Logix-based control assemblies. Protective trip execution is hardware-based and independent of PLC firmware scan timing or deterministic network communication status.
Thermal overload response remains locally processed within the breaker mechanism. During controller restart, network interruption, or backplane communication loss, magnetic short-circuit interruption capability remains active at the fixed instantaneous threshold.
Frequently Asked Questions
Q: Does the 140M-C2E-B16 require external control power for trip functionality?
A: No. Thermal and magnetic trip mechanisms operate as internal electromechanical protection functions without auxiliary control voltage.
Q: Can the breaker be mounted directly on DIN rail assemblies?
A: Yes. The supplied configuration specifies DIN rail mounting for enclosed motor control panel installation.
Q: Is the 140M-C2E-B16 suitable for direct replacement in new installations?
A: The unit is identified as discontinued. New system designs should evaluate compatibility with the replacement model 140MT-C3E-B16.
Field Installation Guidelines
-
Install the breaker inside an enclosed panel due to the IP20 protection classification.
-
Verify motor full-load current before adjusting the 1.0-1.6 A thermal trip range.
-
Separate motor feeder conductors from low-level analog instrumentation wiring to reduce electromagnetic coupling during fault interruption.
-
Confirm DIN rail rigidity and grounding continuity before mounting the breaker assembly.
-
Apply conductor torque according to panel design documentation and terminal labeling.
-
Perform insulation resistance and continuity testing before energizing the protected motor branch circuit.
-
Do not bypass upstream short-circuit coordination requirements with contactors or branch protection devices.
