SG65-63 6A to 63A Low Voltage Miniature Circuit Breaker MCB with 6KA Breaking Capacity

The SG65-63 series miniature Circuit Breakers represent advanced electrical protection technology for low voltage applications. These MCBs feature a compact design with superior breaking capacity and reliable overload/short circuit protection.

With rated currents ranging from 6A to 63A and available in 1P, 2P, 3P, and 4P configurations, these breakers are suitable for diverse electrical distribution requirements. The robust construction using flame-retardant PA66 nylon material ensures safety and durability in various environmental conditions.

Key technical specifications include a rated operational voltage of 230/400V AC, 50/60Hz frequency, and impressive 10,000 mechanical operations lifespan. The breakers offer IP20 protection degree and can endure ambient temperatures up to 55°C.

These MCBs comply with international standards IEC60898 and GB10963.1, featuring multiple certifications including CE, CB, and CCC. The product line includes options for both lighting and motor protection applications.

Typical applications include residential buildings, commercial offices, and industrial facilities where reliable circuit protection is required. The breakers provide effective protection against overloads and short circuits while maintaining stable performance throughout their operational life.

The current release characteristics demonstrate precise tripping performance across different load conditions. Testing includes comprehensive evaluations at various current multiples (1.13In to 14In) with specified trip times for different protection modes (B, C, D).
