ABB MCB, B-Type Tripping, 50A Current Rating - S200 Series - 2CDS251001R0505 S201-B50 Keep electrical currents in their place with this MCB from ABB. It has two tripping mechanisms – a thermal release tackles overloads and an electromechanical device safeguards against short circuits. Thanks to its B-type characteristic, it trips instantly when it detects rogue loads between 3 and 5 times its 50A rating, so people and equipment are protected from small spikes and surges. For convenient fitting, the unit can be connected via a busbar, as well as flexible or rigid conductors. As there are failsafe cylinder-lift terminals that securely grab and position your wires, you'll have no trouble hooking it up.
