ABB MCB, 10kA Short-Circuit Capacity, IP20 Rating - S400M Series - S401M-B4
Use this MCB from ABB to protect people and equipment in your workspace from the harmful effects of overvoltage. As a type B breaking component, it trips quickly to break the circuit and stop electrical energy whenever it's supplied with between 3 and 5 times the 4A rated load. This makes it a practical choice in lower-powered residential settings as its quick tripping action helps to ensure effective protection when even slight overcurrent faults occur. As part of ABB's innovative SMISSLINE TP plug-in distribution system, it's specifically designed for easy mounting and quick dismounting with the assurance of touch protection.
