GDDC4-63 DC MCB Overview

الـ GDDC4-63 DC MCB is a high-performance 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 فولت تيار مستمر, 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 تكوينات 1P و2P و3P و4P, 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 6000 أمبير / 10000 أمبير, 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.
