Swiftly puts the brakes on faulty currents in your system with this MCB from ABB. It breaks an attached circuit when it detects a short-circuit or current overload to protect downstream machines from electrical damage. The unit's type-C tripping characteristic means it trips at between 5 and 10 times its 1A current rating, making it suitable for electrical systems prone to high inductive loads. Mounting this device takes just a jiffy as you clip it directly to a DIN rail.
