The SG65-63 series miniature circuit breaker represents advanced electrical protection technology designed for modern power distribution systems. This MCB features a compact design with superior breaking capacity and reliable overload/short-circuit protection functions.
With rated currents ranging from 6A to 63A and available in 1P, 2P, 3P or 4P configurations, this circuit breaker provides flexible solutions for various electrical applications. The device operates at 230/400VAC with 50/60Hz frequency, making it suitable for global electrical standards.
The breaker's robust construction uses high-quality PA66 nylon material with excellent flame-retardant properties (UL94 V-0 rating) and impact resistance. The IP20 protection degree ensures safe operation in standard electrical environments while maintaining a sleek, space-saving design.
Key technical advantages include a mechanical lifespan of 10,000 operations and thermal endurance up to 55°C with 95% relative humidity. The 10KA breaking capacity provides superior protection against electrical faults, while the precise current release mechanism ensures accurate tripping characteristics according to IEC60898 standards.
This MCB series offers three protection curves (B, C, D types) to match different load characteristics: B-type for residential lighting, C-type for commercial applications with moderate inrush currents, and D-type for circuits with high inrush currents like motors and transformers.
Installation is simplified with screw-type terminals accepting conductors up to 25mm². The product carries multiple international certifications including CE, CB, CCC, and ISO9001, ensuring compliance with global safety standards for electrical distribution equipment.
Typical applications include: Residential/commercial building power distribution, Lighting circuit protection, Equipment overload protection, Motor control circuits, and general electrical system protection where reliable circuit interruption is required.
