Allen-Bradley 140M-C2E-B10 140M Motor Protection Circuit Breaker

Product Overview

The Allen-Bradley 140M-C2E-B10 functions as a specialized, high-performance motor protection circuit breaker within industrial automation frameworks. This 3-pole device integrates local disconnection, short-circuit protection, and thermal overload protection into a single compact housing. It shields downstream three-phase motors from catastrophic electrical damage and ensures safe, predictable system isolation.

Engineering Advantages

• Consolidates Panel Space: This single module replaces the separate traditional combination of a molded-case circuit breaker and an overload relay. This consolidation slashes control panel footprint requirements and significantly reduces internal power wiring complexity.

• Dual-Action Fault Protection: The internal thermomagnetic switch-off mechanism monitors the circuit continuously. The thermal component handles sustained overloads according to Class 10 trip parameters, while the magnetic element activates instantly at 13 A to interrupt high-energy short circuits.

• Simplifies High-Voltage Integration: The device handles operational voltages up to 690V AC and manages 3-phase motor configurations up to 0.75 HP at 575V AC, allowing direct deployment in standard heavy-industrial power grids.

• Positive Status Control: The ergonomic turn button provides crisp tactile feedback and distinct visual indication of the breaker's status (ON/OFF/TRIPPED), accelerating troubleshooting routines during field maintenance.

FAQs

• Does this motor protection breaker arrive in a factory-sealed box?

  Yes. We ship the 140M-C2E-B10 as a 100% brand new, genuine original manufacturer item in its authentic Rockwell Automation factory packaging.

• What type of motor load does the Class 10 trip rating accommodate?

  The Class 10 trip rating guarantees that the breaker will trip within 10 seconds or less at six times its thermal current setting. This parameter safely protects standard, continuous-run industrial motors that do not experience prolonged high-inertia startup cycles.

• Can I mount this circuit breaker onto standard DIN rails?

  Yes. The 140M series housing snaps directly onto standard 35mm DIN rails, which minimizes installation times inside heavy-duty machine control enclosures. Ensure proper vertical alignment and adequate ventilation clearance inside the panel according to manufacturer specifications.
