USED ABB BU201M K30A

The ABB BU201M K30A is a single-pole miniature circuit breaker (MCB) featuring a K-characteristic tripping curve, rated at 30 amperes. Designed for branch circuit protection in industrial and commercial electrical systems, it provides thermal-magnetic trip protection against overloads and short circuits. The K-curve characteristic makes it ideal for motor and transformer protection applications where high inrush currents are present. The breaker mounts on a standard 35mm DIN rail, features finger-safe screw terminals, a sealable actuator, and complies with UL 489, CSA 22.2 No. 5, and IEC/EN 60947-2 standards.
