Description
Built for heavy-duty residential applications like ranges and HVAC equipment, the Federal Pacific NA250 supplies 50A of two-pole protection. This component mounts into classic Stab-Lok load centers, providing a secure plug-on connection. Serving as a direct substitute for the UBIF250N, it utilizes a full-size two-inch footprint to maintain proper panel spacing. The breaker features an internal common trip mechanism to disconnect both poles simultaneously during a fault, rated at 10kAIC.
