Wadsworth A240NI - 40A, 2-Pole, Circuit Breaker

Protect critical electrical systems with the Wadsworth A240NI – 40A, 2-Pole, Circuit Breaker. This rugged device is built to deliver dependable overcurrent protection in panelboards, switchboards, and control panels across industrial, commercial, and OEM environments.

With a 40A current rating and a true 2-pole configuration, the A240NI interrupts both conductors for safer, simultaneous shutdown on faults. It's designed for installations where space and reliability matter, and where safeguarding motors, drives, and distribution circuits is essential.

Designed for robust, practical use

• Two-pole protection for 240V circuits: interrupts both hot lines together, reducing arcing and simplifying compliance in systems where dual-conductor protection is required.
• 40A protection: tailored for common branch circuits feeding motors, heating elements, and other equipment in MCCs and distribution panels.
• Versatile mounting in panelboards, switchboards, and control panels: a fit for new builds and retrofits alike, enabling clean, organized protection across equipment enclosures.
• Industrial-grade reliability: engineered to perform in demanding environments, supporting long service life in continuous operation contexts.

Ideal use scenarios

Best suited for motor control centers (MCCs), distribution panels, and control enclosures in factories, warehouses, and commercial facilities. OEMs can streamline panel designs by standardizing on a single, reliable 2-pole breaker for 40A circuits.

Practical installation guidance

Before installation, verify that your panel supports a 2-pole 40A circuit breaker in the Wadsworth A240NI family. Ensure wiring meets your panel’s specifications and that the breaker is seated securely in its bus to maintain safe operation.
