Information About 140M-C2E-C10

The 140M-C2E-C10 is part of the Allen-Bradley Bulletin 140M family of motor protection circuit breakers, offering coordinated short-circuit protection and manual switching capability for three-phase motors. This C-frame model features an adjustable thermal overload setting between 6.3 and 10 A, paired with a fixed magnetic trip element designed for fast response during fault conditions. It provides high current-limiting performance and visible trip indication, making troubleshooting and maintenance more efficient. With a 32 A frame rating, UL motor-load recognition, and compact DIN-rail mounting, it is suitable for a wide range of motor starters and industrial equipment where overload protection is provided separately.

Key Features:

  • Adjustable 6.3–10 A Thermal Setting: Allows precise matching to motor full-load current requirements.
  • Fixed Magnetic Trip: Delivers fast short-circuit protection for motor branch circuits.
  • High Current-Limiting Capability: Reduces let-through energy during fault conditions to protect downstream components.
  • Visible Trip Indication: Provides clear status for fast diagnostics and maintenance.
  • UL Listed for Motor Loads: Ensures suitability for industrial motor protection applications.
  • C-Frame Design: Supports up to 32 A frame rating for robust system integration.
  • DIN-Rail Mounting: Enables quick installation into control cabinets and motor starter assemblies.
  • Wide Current Range Support: Part of a family covering 0.16–1200 A, ensuring consistent system design.

The 140M-C2E-C10 delivers the reliability and precision required for dependable short-circuit protection, coordinated motor control, and industrial branch-circuit safety.

Frequently Asked Questions about 140M-C2E-C10
Question: What is the Allen-Bradley 140M-C2E-C10?
Date Update:13/06/2025
Answer:

The 140M-C2E-C10 is a Motor Protection Circuit Breaker designed by Allen-Bradley. It is used to protect motors from electrical faults such as overload, short circuits, and phase loss. This breaker offers reliable motor protection and helps in preventing damage to the motor and connected equipment.

Question: How does the 140M-C2E-C10 breaker protect the motor?
Date Update:13/06/2025
Answer:

The 140M-C2E-C10 breaker provides several layers of protection:

  • Overload Protection: It monitors the motor's current and trips if it exceeds the set limit for too long.
  • Short Circuit Protection: The breaker trips in case of a short circuit to prevent damage to the motor and wiring.
  • Phase Loss Protection: It can detect if a phase is lost, preventing the motor from running in an unsafe condition.
  • Under-voltage Protection (optional feature depending on configuration).
Question: How do I install the 140M-C2E-C10 breaker?
Date Update:13/06/2025
Answer:

To install the 140M-C2E-C10 motor protection circuit breaker:

  1. Mount the breaker on a DIN rail or in a panel suitable for industrial applications.
  2. Connect the power supply to the input terminals and the motor connections to the output terminals.
  3. Ensure that the breaker’s current settings are adjusted according to the motor’s full load amperage (FLA).
  4. Secure all wiring and ensure there are no loose connections before applying power to the circuit.
Question: How do I reset the 140M-C2E-C10 breaker after it trips?
Date Update:13/06/2025
Answer:

To reset the 140M-C2E-C10 breaker after it trips, first, identify and correct the cause of the trip (e.g., overload, short circuit, phase loss). Once the issue has been resolved:

  1. Ensure the motor is in a safe condition.
  2. Move the breaker’s handle or switch back to the ON position to reset it.
  3. Verify that the motor is functioning properly before continuing normal operation.
Question: What should I do if the 140M-C2E-C10 breaker continues to trip?
Date Update:13/06/2025
Answer:

If the 140M-C2E-C10 breaker continues to trip, it indicates a persistent fault in the system. The following checks should be performed:

  • Check the motor for overload or mechanical issues that may be causing excessive current draw.
  • Inspect wiring for short circuits, grounding issues, or other faults.
  • Verify phase loss or imbalance in a three-phase motor system.
  • Ensure that the breaker’s current setting is correct for the motor’s full load amperage (FLA).
  • If the issue persists, consult a qualified technician for further troubleshooting.
