Federal Pacific Electric NA230 U Circuit Breaker

The Federal Pacific Electric NA230 U is a 30-amp, two-pole circuit breaker rated for 240 volts. As an overcurrent protection device, it interrupts current when faults occur on 240V circuits to prevent conductor overheating and protect connected equipment. The NA230 U designation identifies a specific 2P, 30A configuration designed to provide 240V protection in electrical distribution systems that require this breaker style. With a two-pole design, it protects both hot conductors of a 240V circuit, ensuring that the circuit is disconnected if an overload or short occurs. This rating targets branch circuits that are expected to draw up to 30 amperes under normal operation, and it trips at or above that level to limit conductor temperatures and potential damage. Breakers like the NA230 U are used to safeguard wiring and devices connected to 240V loads by interrupting power in fault conditions, helping maintain electrical safety within the system. For anyone replacing or specifying a 240V, 30A two-pole breaker, the NA230 U provides the exact configuration described by its model and ratings.
