NEF421080 | Circuit Breaker | 2-Pole

Introducing NEF421080, a rugged industrial circuit breaker engineered for reliability in demanding panels. This 2-Pole device is the ideal choice for maintenance, retrofit, or replacement projects where exact specifications matter. With the NEF421080, you can protect critical equipment while simplifying sourcing through a single, clearly referenced part number.

Why a 2-Pole design matters

A two-pole breaker disconnects both conductors in paired circuits, delivering complete de-energization and safer shutdown of connected equipment. This makes it well-suited for 240V applications, multi‑phase layouts, and motor-driven loads where simultaneous protection on both lines is essential.

Exact fit starts with the part number

When accuracy matters, the NEF421080 is your most reliable compatibility reference. Before ordering, confirm that this 2-Pole circuit breaker matches your panel’s required ratings and mounting configuration. This device is intended for maintenance, retrofit, and replacement scenarios where matching specs are required and a direct part-number match ensures a trouble-free swap.

Key compatibility checks

• Poles: 2-Pole
• Ratings: Verify voltage, current, and trip characteristics against your panel requirements
• Mounting & terminals: Ensure the mounting style and terminal setup align with your enclosure
• Reference: Use the NEF421080 part number as the compatibility guide

Ideal use cases
