LS Electric BK63HU Miniature Circuit Breaker – 2-Pole, 5A, C-Curve, 10kA, 480Y/277V AC, UL 489 Rated

The BK63HU series is engineered for global applications, carrying UL, CSA, and CE certifications. This specific unit is a 2-Pole breaker with a 5 Amp rating and a C-Trip Curve. The C-Curve is the "standard" industrial choice, designed to handle moderate inductive inrush currents (like those from small motors or solenoid valves) without nuisance tripping, while still providing fast short-circuit protection.
