Federal Pacific Electric NBH1030U Circuit Breaker

The Federal Pacific Electric NBH1030U is a single-pole, 30-amp circuit breaker rated for 277 volts. It functions as overcurrent protection in electrical distribution by interrupting current when the load exceeds 30 amps on a 277V branch circuit, helping protect wiring and connected devices from damage. As a 1P device, it protects a single hot conductor path, commonly used for individual commercial or industrial circuits that supply 277V equipment and lighting. This part is intended for installation in systems that require a 277V, 30A, single-pole breaker of this exact form factor. When selecting this breaker, ensure panel compatibility and confirm that the circuit voltage and protective rating match your installation specifications. Typical use cases include branch circuits for lighting or equipment in commercial settings where 277V distribution is standard. Always follow electrical code requirements and install only with the appropriate tools and safety procedures.
