Descripción
GDDC4-63 DC MCB Overview
El GDDC4-63 DC MCB es un producto de alto rendimiento nonpolarity DC miniature circuit breaker developed for overload and short-circuit protection in photovoltaic, energy storage and other low-voltage DC systems. With rated currents from 10A to 63A and system voltage configurations extending up to 1000 V CC, it provides a flexible protection solution for modern DC distribution equipment.
A key advantage of the GDDC4-63 DC MCB is its nonpolarity design. Conventional polarized DC circuit breakers require careful attention to positive and negative terminal orientation. The nonpolarity structure provides greater wiring flexibility during panel assembly and field installation, which is particularly useful in photovoltaic and energy-storage applications.
The series supports Configuraciones de 1P, 2P, 3P y 4P, corresponding to different DC voltage levels. Standard configurations include 1P 250V DC, 2P 500V DC, 3P 750V DC and 4P 1000V DC.
With a rated breaking capacity of 6000A / 10000A, the GDDC4-63 DC MCB is positioned above lower-breaking-capacity models for applications requiring stronger fault-current interruption performance. It complies with IEC/EN60947-2 and supports B, C and D thermo-magnetic trip characteristics.
