Description
GYL9-A-SI SI Type RCCB Product Highlight：
Transient Interference Suppression Design：The GYL9-A-SI is a residual current operated circuit breaker specially developed to suppress transient interference. Its operating time ranges from 40–150 ms, striking an optimal balance between instantaneous (fast-response) and time-delayed types. This unique design enables flexible coordination with both instantaneous and time-delayed breakers, forming a multi-level protection system.
Dual Busbar Wiring Capability：The terminal block features a dual design that supports simultaneous connection of wires and busbars, offering greater installation flexibility for diverse circuit requirements. It accommodates conductor sizes from 1–35 mm² and ensures easy, reliable wiring.
Wide Range of Rated Currents and Pole Configurations：Available rated currents: 16 A, 20 A, 25 A, 32 A, 40 A, 50 A, 63 A, 80 A, and 100 A.Pole configurations: 1P+N or 3P+N.Rated residual operating currents: 0.03 A, 0.1 A, and 0.3 A, meeting the customized needs of various circuits.
High-Durability Materials and Construction：Internal plastic components are made of high-temperature-resistant materials to prevent deformation or performance degradation under temperature fluctuations. It incorporates reinforced flame-retardant nylon and high-quality silver contacts for enhanced durability and fire resistance. The operating mechanism features a free-trip function, ensuring the breaker remains only in the fully closed or fully open position—whether under normal or fault conditions—eliminating the risk of intermediate states.
Modular Design and Expandability：Built on the ID technology platform, it offers excellent flexibility and can be combined with accessories such as auto-reclosers to achieve intelligent expansion. With high sensitivity and robust safety performance, it delivers more reliable leakage protection.
Leakage Fault Indication：Equipped with a built-in leakage fault indicator window, allowing users to quickly identify faults, and faults, thereby improving maintenance efficiency.
GYL9-A-SI SI Type RCCB Application Scenarios：
The GYL9-A-SI is specifically suited for environments requiring high immunity to nuisance tripping, delivering outstanding performance in the presence of pulsating DC or high-frequency interference:
- Residential and Commercial Buildings: Ideal for smart homes, offices, and shopping malls where electronic devices (such as computers, chargers, and appliances) are densely used, preventing unwanted tripping caused by transient disturbances.
- Industrial Environments: Perfect for automated production lines, variable frequency drive (VFD) systems, and medical equipment, providing reliable leakage protection in demanding conditions.
- Modern High-Tech Applications: Electronic-intensive settings such as data centers, photovoltaic (PV) systems, and other installations with complex electromagnetic environments.
