Product description

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.

  • Three-pole design for three-phase safety — ensures simultaneous disconnection of all live lines, reducing shock risk and simplifying wiring layouts.
  • 40A protection — precisely matches typical motor and equipment loads in industrial environments, helping prevent nuisance trips while safeguarding circuitry.
  • 240V compatibility — ideal for common distribution panels and MCCs that run on 240V three-phase power.
  • Exact-fit replacement — part number NFS340 provides a reliable reference point for compatibility and streamlined inventory management in service fleets.
  • Maintenance-friendly substitution — designed to slot into existing panels with minimal adjustments when replacing worn or failed breakers.

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.

Practical tips for best results:

  • Keep a spare NFS340 on hand for quick replacements in critical downtime scenarios.
  • Document the exact panel model and wiring configuration to verify compatibility with the NFS340’s three-pole, 240V setup.
  • After installation, torque connections to the panel manufacturer’s specifications to maintain reliable performance.
