NB232050 - 50Amp Circuit Breaker

NB232050 - 50Amp Circuit Breaker

The NB232050 50 Amp 3 Pole Circuit Breaker is designed for three-phase electrical systems that require steady, reliable protection. With a 50 amp rating and 10k AIC at 240VAC, it helps protect wiring and connected equipment from overloads and short circuits. The thermal magnetic trip mechanism reacts to both long-term overcurrent conditions and sudden faults, helping reduce the risk of equipment damage. Its bolt-on design attaches securely to compatible panels, creating a solid connection that stays in place over time.

This breaker is commonly used as a replacement unit in existing panels or for routine electrical maintenance where a properly rated 3 pole, 50A breaker is required.

Key Features and Benefits
