LIVE Electrical DCM420C 4-Pole 20A C Curve 6kA DC Miniature Circuit Breaker

Product Overview

The LIVE Electrical DCM420C 4-Pole DC Miniature Circuit Breaker provides reliable protection for direct current (DC) circuits operating up to 1000V DC. With a rated current of 20A and a 6kA breaking capacity, this MCB ensures safe disconnection in the event of short circuits or overloads. Its C-curve thermo-magnetic release characteristic makes it particularly suitable for applications with moderate inrush currents, such as solar PV systems, DC control panels, and energy storage installations.

Engineered in compliance with IEC/EN 60898-2 standards, the DCM420C combines durability, precision, and safety. Its compact modular design supports DIN rail mounting for straightforward installation, while the IP20 contact protection rating ensures user safety and operational integrity within enclosed environments.
