The 45 A rating at 120/240 V provides strong branch-circuit protection with a 42 kAIC interrupt rating, enabling fast fault clearance and reducing the risk of equipment damage and downtime in demanding panels. The 1-Inch plug-on design and single-pole configuration simplify field installation and future replacements, allowing quick upgrades in Type BR Loadcenters without excessive rewiring. A common trip across the feeder and branch circuits promotes safe, coordinated shutdowns during maintenance and fault events, enhancing safety and regulatory compliance. Wiring flexibility includes #14-4 AWG Cu/Al conductors, with a compact footprint (3 in L x 3 in H x 2 in W) and a weight of 0.3 lb, making it ideal for space-constrained installations. Compliance and warranty details (UL 490, Federal Specifications W-C376, limited lifetime residential/1-year commercial) support long-term reliability and predictable maintenance costs. Catalog notes indicate versatile availability across 10–150 A with switching duty, HACR, shunt trip, and high-magnetic settings for BR line flexibility.
