NEF427020 | Circuit Breaker | 20A | 2-Pole | 480V

NEF427020 is a rugged industrial circuit breaker engineered for durability in demanding environments. With a 20A rating, a 2-pole configuration, and 480V compatibility, it’s a reliable choice for maintenance, retrofit, and replacement projects where exact specifications matter. When you’re updating panels or upgrading protection, choosing the right part number is essential, and NEF427020 is the reference you want to rely on.

Why this 2-Pole, 480V design matters

Two-pole construction means both live conductors are interrupted together, providing safer, more synchronized protection for 480V layouts. This is especially important in industrial distributions where shutting off all hot lines reduces arc flash risk and protects connected equipment during service or fault conditions. The 20A rating targets common branch circuits and control circuits, helping you balance protection with normal operating load.

Where it fits and how it helps

• Maintenance: swap-in units that match the original installer’s specifications to minimize downtime.
• Retrofit: upgrade legacy systems to current protection standards without overhauling the panel architecture.
• Replacement: if you’re restoring an aging panel, this exact part number ensures compatibility and consistent protection characteristics.
• Panel compatibility: ideal for industrial panels configured for 480V systems requiring a 2-pole, 20A device.
