Allen-Bradley 140M-C2E-B40-MT 4A 3-Pole 600 V Circuit Breaker

Meet the Allen-Bradley 140M-C2E-B40-MT — a purpose-built circuit breaker engineered to protect your three‑phase power systems with precision. rated at 4 A, this 3‑pole unit is designed to intercept faults quickly and keep critical equipment safe in demanding industrial environments. With a 600 V maximum voltage rating, it’s ready to pair with a wide range of control panels, MCCs, and machine circuits.

• Three-pole protection provides balanced shutdown across all phases, helping prevent damage from phase imbalance and short circuits in three-phase networks.
• 4 A current rating targets small-to-medium loads and control circuits, reducing nuisance trips while still delivering reliable fault protection for sensitive equipment.
• 600 V rating supports typical industrial power distribution, making it suitable for many manufacturing and automation applications.
• Part number 140M-C2E-B40-MT ties this breaker to the Allen-Bradley 140M family, simplifying sourcing, replacement, and compatibility within existing panels.
• Brand reliability from Allen-Bradley, a trusted name in industrial electrical protection, ensuring consistent performance and availability of spare parts.

This breaker is ideal for protecting three-phase motors, conveyors, automated machinery, and control circuits within manufacturing lines and industrial environments. It’s a practical choice for panel builders and maintenance teams looking to upgrade or replace aging protection devices in 140M‑series installations.

Why choose this specific model? The combination of a 4 A rating with a 3-pole design and a 600 V capability gives you focused protection for smaller loads within robust, three-phase systems. Its alignment with the Allen-Bradley 140M family ensures straightforward compatibility with existing equipment and a reliable supply chain for parts and service.

Practical tips for use: verify the system voltage and phase configuration matches a 3‑phase, 600 V environment; confirm the load characteristics align with the 4 A rating to minimize nuisance trips; and plan for easy maintenance by documenting the part number for quick replacements in your electrical cabinet inventory.
