The LIVE Electrical DCM440C 4-Pole DC Miniature Circuit Breaker provides high-performance circuit protection for direct current (DC) systems operating up to 1000V DC. With a rated current of 40A and a 6kA breaking capacity, it ensures reliable disconnection and overload protection in demanding DC applications. The C-curve thermo-magnetic trip characteristic makes it ideal for installations with moderate inrush currents, such as solar PV arrays, EV charging systems, and battery storage setups.

Fully compliant with IEC/EN 60898-2, the DCM440C combines safety, precision, and easy installation. Its IP20-rated terminals offer touch-safe protection, while the DIN rail mountable design ensures straightforward integration into any control or power distribution enclosure.
