The GDDC5-63 2-Pole 20A DC Miniature Circuit Breaker (MCB) is designed for precise overload and short-circuit protection in two-pole DC circuits up to 500V DC. This 20A model is ideal for medium-current branch protection in photovoltaic arrays, battery energy storage systems, telecom DC distribution, and industrial DC control panels. With a footprint of 36 mm width, it supports infrequent manual switching under normal conditions and features a front contact position indicator for quick operational status checks. For other system configurations, matching 1P (250V DC) and 4P (1000V DC) versions are available.
