DZ47LE-63 Residual Current Circuit Breaker 1-4 Pole with CE Certificate for Electrical Safety

The DZ47LE-63 series residual current circuit breaker represents advanced electrical protection technology designed for comprehensive safety in power distribution systems. This sophisticated device combines the functionality of a high-breaking miniature circuit breaker with an integrated current leakage release mechanism, providing multi-layered protection for both personnel and equipment.

Engineered for AC power systems operating at 50Hz frequency, this circuit breaker is compatible with single-phase 230V and three-phase 400V applications. The device automatically interrupts power supply when it detects electric shock situations or when leakage current exceeds predetermined thresholds, thereby preventing potential hazards and equipment damage caused by electrical faults.

Beyond its primary leakage protection function, the DZ47LE-63 offers robust protection against overload and short circuit conditions. The circuit breaker can also serve as an infrequent switching device under normal operating conditions. Additional protective features including over voltage and under voltage protection can be incorporated based on specific customer requirements, making it a versatile solution for various electrical applications.

The structural design incorporates a zero sequence current transformer, electronic control panel, current leakage release mechanism, and the main circuit breaker unit. This integrated approach ensures reliable performance while maintaining compact dimensions suitable for standard electrical enclosures. The device complies with international standards IEC1009-1 and GB16917.1, guaranteeing global compatibility and safety compliance.

Manufactured using flame-retardant PA66 nylon material, the circuit breaker housing provides excellent thermal stability and mechanical strength. The IP20 protection degree ensures adequate protection against solid objects while the DIN rail mounting design facilitates easy installation in various electrical distribution panels and control systems.

With a mechanical lifespan exceeding 20,000 operations and comprehensive certification including CE, CB, and CCC, this residual current circuit breaker delivers reliable long-term performance. The availability of multiple pole configurations (1+N, 2, 3, 3+N, 4 poles) and current ratings from 6A to 63A makes it suitable for diverse residential, commercial, and industrial applications.
