A 40A-2 - 40A, 2-Pole, Circuit Breaker

The A 40A-2 is a rugged 40A, 2-Pole circuit breaker engineered to guard electrical circuits in demanding environments. With its 2-pole configuration, it ensures simultaneous protection and disconnection of both live lines, enhancing safety in 240V and multi-wire applications.

Designed for flexible use in panelboards, switchboards, and control panels, this breaker is a trusted choice for industrial, commercial, and OEM setups where dependable overcurrent protection and safe operation are critical in distribution panels and motor control centers.

Key benefits

• Precise protection: 40A current rating provides targeted protection for circuits with significant load while minimizing unnecessary trips.
• Two-pole reliability: Simultaneous disconnection of both conductors improves safety and aids in compliant shutdowns during faults.
• Versatile installation locations: Suitable for panelboards, switchboards, and control panels found in industrial facilities and OEM equipment.
• Simple integration: A straightforward, standard breaker design that complements existing protection schemes in distribution panels and motor control centers.

Who it's for: Electricians, panel shop integrators, facility engineers, and OEM designers who need dependable, easy-to-specify overcurrent protection for critical circuits in industrial and commercial settings.

Practical use cases include powering motor control centers, feeding critical distribution panels, or protecting feeder circuits in factory automation setups where a reliable 40A, 2-pole breaker is essential for safe, trouble-free operation.

Why choose the A 40A-2 over other options? Its 2-pole arrangement pairs well with 240V circuits and shared loads where two hot legs must trip together, simplifying protection coordination and reducing the risk of one leg remaining energized after a fault.
