Allen-Bradley 140M-C2E-B40-KRY 40A 3-Pole Circuit Breaker

Meet the Allen-Bradley 140M-C2E-B40-KRY 40A 3-Pole Circuit Breaker — a precise, dependable protection device designed for demanding industrial and automation environments. This part, identified by the exact 140M-C2E-B40-KRY model number, delivers reliable current interruption across a three-phase system, helping protect motors, drives, and control circuitry from overloads and short circuits.

Key features that matter in real-world applications:

• 40 A current rating provides solid protection for circuits demanding robust, consistent performance while preventing overheating and equipment damage.
• 3-pole design ensures simultaneous protection across all three phases, maintaining balance and preventing phase-related faults in three-phase installations.
• Part number clarity ensures you’re selecting a precise replacement or compatible component for Allen-Bradley panels and configurations that use the 140M family.
• trusted brand Allen-Bradley engineering behind the device offers confidence in long-term reliability and availability for maintenance or replacements in critical systems.

Why this model is a smart choice for your setup:

• Exact fit for 140M-series integrations — designed to align with existing 140M installations, simplifying stocking and replacement without rework.
• Balanced protection — the 3-pole arrangement provides coordinated shutdown across all phases, which is essential for motor loads, conveyors, and automated machinery.
• Operational resilience — quick interruption during overloads or faults minimizes downtime and helps extend the life of connected equipment.

Ideal use scenarios:

• Industrial control panels and machine automation where three‑phase protection is required.
• Motor control circuits in manufacturing lines, packaging systems, and material handling setups.
• Distribution sections within automation cabinets where reliable, predictable trip behavior is essential.

Practical considerations for installation and maintenance:

• Verify compatibility with your panel’s frame and bus configuration before installation.
• Follow standard electrical safety practices; de-energize the system prior to replacement or servicing.
• Refer to local codes and guidelines to ensure proper sizing and protection for your specific load profile and startup surges.

The Allen-Bradley 140M-C2E-B40-KRY 40A 3-Pole Circuit Breaker is a purpose-built solution for safeguarding three-phase systems in industrial environments, delivering dependable protection, straightforward replacement, and peace of mind for ongoing operation and maintenance.
