NB260 | Circuit Breaker | 2-Pole | 240V

Meet the NB260 2-Pole Circuit Breaker—the practical, no-nonsense protection solution for 240V electrical circuits. Designed for maintenance, retrofit, and replacement projects, this breaker delivers reliable overcurrent protection when exact specifications matter, helping keep equipment running smoothly and safely.

When you’re updating or expanding a 240V panel, you need a part you can trust. The NB260 is built for two-pole protection, ensuring both hot lines are interrupted together during an overcurrent event. That coordinated disconnection is essential for preventing equipment damage and enhancing operator safety in industrial and commercial environments.

Key details
