GA&DA GDDCM1-250 DC Molded Case Circuit Breaker 3P 250A 1500V

GDDCM1-250-3P DC MCCB Overview

الـ GDDCM1-250-3P DC MCCB is a three-pole molded case circuit breaker designed for high-voltage direct current distribution and protection. With a 250A rated current and operating voltage options extending up to 1500V DC, it is suitable for photovoltaic power generation, battery energy storage, industrial DC distribution, and other applications where higher current capacity and dependable fault protection are required.

Unlike standard miniature circuit breakers used for lower-current branch circuits, this molded case design is intended for larger DC feeders and power distribution systems. The robust housing provides mechanical strength and electrical insulation, while the clearly visible operating handle allows operators to identify the switching status quickly during installation, inspection, and maintenance.

The product markings indicate compatibility with DC1000V, DC1250V, and DC1500V applications. Its short-circuit breaking capability reaches 25kA at DC1000V and DC1250V, while the DC1500V configuration is marked at 20 كيلو أمبير. This gives system designers greater flexibility when selecting a breaker for different photovoltaic or battery-system voltage levels.

الـ GDDCM1-250-3P DC MCCB also complies with IEC 60947-2, making it suitable for professional low-voltage DC distribution equipment. Its three-pole structure is particularly useful in high-voltage DC circuit arrangements that require multi-pole isolation and coordinated disconnection.
