NA380 | Circuit Breaker | 80A | 3-Pole | 240V

The NA380 Circuit Breaker is an industrial-grade protective device designed for reliability in 240V, three‑phase power systems. With an 80A rating and a 3‑pole configuration, it delivers balanced, dependable overcurrent protection across all three phases, making it ideal for maintenance, retrofit, and replacement projects where exact specifications are required.

Key specifications

• Amperage: 80A
• Poles: 3‑Pole
• Voltage: 240V

What sets NA380 apart

Unlike generic substitutes, the NA380 is specified by part number to ensure precise compatibility. It supports three‑phase protection in 240V panels and is optimized for quick swaps in maintenance and retrofit workflows, helping you minimize downtime while preserving system integrity.

Ideal use cases

• Maintenance and service work on existing 3‑pole, 240V circuits
• Retrofit projects where a like‑for‑like NA380‑spec component is required
• Replacement for failed breakers in industrial control panels with matching ratings

How to ensure compatibility

Quick checks to verify fit: confirm your panel operates at 240V with three poles and an 80A protection level. The part number NA380 is the best reference for compatibility—confirm fit and ratings before ordering.

Practical guidance for installation and use

• Always power down and test circuits before removing or installing breakers
• Verify the breaker’s mounting style and bus configuration matches your panel
• Follow safety protocols and local electrical codes to ensure a safe, compliant installation

In short, the NA380 is a purpose-built 3‑pole, 240V, 80A circuit breaker engineered for industrial environments. Choose it when your system aligns with its specs and you need a clearly defined part number reference that supports reliable replacement, retrofit, and ongoing protection of critical loads.
