Protect your electrical appliances from short circuits and overvoltages with this MCB from ABB. The device features two tripping mechanisms – a delayed thermal system, which defends against overloads, and an electromechanical system to safeguard your network from short circuits. As it has type-C tripping characteristics, it cuts the circuit at 5 to 10 times the 4A current rating, so is a practical choice for low-current-consuming applications. You can quickly and simply mount this circuit breaker on a DIN rail without needing any tools.
