ABB MCB, Type B Tripping Characteristics, Screw Terminals - S400M Series - S401M-B16

When you need to protect an extra circuit in your SMISSLINE TP system, this MCB from ABB snaps on swiftly to save you time. It plugs straight into your socket base (246-1929) in any position, so you'll find it's no hassle to add or switch around this device in your commercial, industrial or critical power application. Electro-mechanical and thermal mechanisms give you all-around protection from short circuits and overloads. The MCB's type B breaking characteristic ensures it trips the moment small surges between 3 and 5 times the rated load of 16A are detected. This means you'll get no nasty shocks when working with your equipment.
