Shield equipment from electrical hazards and remove the risk of harm to users with this MCB from ABB. As a type-B breaker, it's a great shout for protecting domestic low-voltage circuits whenever they receive between three and five times the rated load of 20A. Its short-circuit breaking capacity of up to 20kA and impulse withstand voltage to 4kV make it a safety stalwart that prevents current faults or voltage surges from causing problems. You'll find it's a breeze to create robust wired connections thanks to the unit's screw terminals. These have a low tightening torque of 2.8Nm, so all you need to get the job done by hand is a simple Posidriv screwdriver.
