DZ47-63 High Breaking Capacity Miniature Circuit Breaker MCB for Overcurrent Protection

The DZ47-63 series miniature circuit breaker is a high-performance electrical protection device designed for low voltage distribution systems. With its advanced arc-extinguishing technology and robust PA66 flame-retardant housing, this MCB provides reliable overload and short circuit protection for both residential and commercial applications.

This circuit breaker complies with international standards IEC60898 and GB10963.1, featuring a compact design suitable for DIN rail mounting. The product is available in multiple configurations including 1P, 2P, 3P and 4P options, with rated currents ranging from 6A to 63A to meet various circuit protection requirements.

Key technical specifications include a rated operational voltage of 230/400V AC, frequency compatibility of 50/60Hz, and breaking capacity of 4KA (C curve) or 6KA (D curve). The thermal-magnetic trip mechanism ensures precise protection characteristics with mechanical endurance exceeding 10,000 operations.

The MCB features clear trip indication and quick-make/quick-break contacts for enhanced safety. Its current-limiting design helps protect downstream equipment by rapidly interrupting fault currents. The product is particularly suitable for lighting circuits (C characteristic) and motor protection (D characteristic) applications.

With CE, CB and CCC certifications, this miniature circuit breaker meets global quality and safety standards. The IP20 protection grade ensures basic protection against accidental contact while maintaining proper ventilation for thermal performance.
