The SRD5-63 series is a fully upgraded Residual Current Circuit Breaker (RCCB) tailored for AC 50Hz power systems, supporting single-phase 230V and three-phase 400V/415V configurations. As a multifunctional RCBO (Residual Current Circuit Breaker with Overload Protection) and ELCB (Earth Leakage Circuit Breaker), it delivers critical safety by automatically cutting off power when electric shock occurs or leakage current exceeds the preset threshold. Compliant with international standards IEC/EN 61008-1 and IEC/EN 62423, this Type B residual current protector stands out for safeguarding personnel and equipment across industrial, medical, charging pile, and elevator sectors. Unlike standard A-type protectors, it effectively mitigates AC, pulsating DC, compound (F-type), smooth DC, and high-frequency (1kHz) residual currents, making it indispensable for circuits with rectifiers, inverters, and frequency converters.
The SRD5-63 excels at detecting and neutralizing diverse residual current types—from common AC and pulsating DC (A-type) to complex compound DC (F-type), smooth DC, and high-frequency signals up to 1kHz. This ensures all-around protection in modern mixed-current electrical systems, eliminating hidden hazards.
Beyond leakage protection, this RCBO integrates robust overload protection and short circuit protection, eliminating the need for additional devices. With a rated short circuit capacity of 6000A and rated making/breaking capacity of 1000A, it rapidly interrupts fault currents to minimize equipment damage.
Available in 1P+N and 3P+N pole configurations, the SRD5-63 supports rated voltages of 230V1P+N and 415V3P+N, with rated currents ranging from 16A to 63A. Rated sensitivity (I∆n) options (0.03A, 0.1A, 0.3A) cater to different safety requirements in various scenarios.
Boasting a mechanical life of 20,000 operations and electrical life of 1000 cycles, the SRD5-63 is built for long-term use. Its IP20 protection degree and operating temperature range of -25℃~+40℃ ensure stability in harsh industrial and outdoor environments.
To meet specific needs, the Residual Current Circuit Breaker offers optional over voltage protection and under voltage protection, providing tailored safety solutions for specialized applications like medical equipment or charging piles.
