NBN221030 | Circuit Breaker | 30A | 2-Pole | 240V

In demanding industrial panels, reliability isn’t optional—it's essential. The NBN221030 Circuit Breaker is a precise, drop-in solution designed for maintenance, retrofit, and replacement tasks where exact specifications matter. With a 30A rating and a 2-pole configuration for 240V circuits, this unit delivers dependable overload protection while ensuring both hot legs are isolated for safe service operations.

• Amperage: 30A
• Poles: 2-Pole
• Voltage: 240V
• Part reference: NBN221030 — the exact compatibility reference for matching specs
• Ideal for maintenance, retrofit, and replacement projects where precise specifications are required

Why the NBN221030 stands out in industrial panels

This two-pole breaker is engineered to protect essential circuits in complex electrical environments. The 240V rating makes it suitable for standard industrial distribution networks, helping prevent damage to cables, motors, controllers, and downstream equipment. By interrupting current on both conductors, it provides robust safety and simplifies servicing compared with single-pole alternatives.

Practical use cases and benefits

• Maintenance scenarios: quickly swap in a like-for-like 30A, 2-pole, 240V breaker to restore safe, code-compliant operation without compatibility guesswork.
• Retrofit projects: upgrade or replace aging components with a part that exactly matches amperage, pole count, and voltage for seamless integration.
• Replacement decisions: rely on the precise part number NBN221030 to avoid mismatches in panels designed for this form factor.
• Safety and isolation: simultaneous disconnection of both lines enhances protection during servicing and reduces risk of residual energization.

Installation notes and best practices

Before ordering, confirm fit and ratings against your panel documentation. Use the part number NBN221030 as the primary compatibility reference, ensuring your system operates at 240V and requires 2-pole protection at 30A. When installing, power should be de-energized, follow your panel manufacturer’s guidelines for mounting and connection, and keep spare breakers accessible for future maintenance needs.
