Meet the NFS340 — a purpose-built industrial circuit breaker engineered for dependable protection in maintenance, retrofit, and replacement projects. With a 40A rating, 3 poles, and 240V operation, this unit is designed to meet exacting specifications in three-phase systems where reliable disconnection and fast fault isolation matter.
Important: Confirm fit and ratings before ordering. The NFS340 part number is the best reference for compatibility with your panel, bus configuration, and intended application. Always compare mounting style and electrical characteristics to ensure a seamless swap.
Ideal for electrical maintenance teams, retrofit projects updating to a 40A three-pole 240V solution, or replacing worn breakers in industrial panels and motor control centers. Use cases include protecting feeders to motors, controlling distribution in manufacturing lines, and serving as a reliable service disconnect in three-phase systems.
