GYL9-AC Type AC RCD Product Highlight：

Optimized for Power-Frequency Sinusoidal AC Leakage Protection:The GYL9-AC is specifically engineered for linear loads (resistive or inductive loads). It accurately detects both suddenly applied instantaneous leakage currents and slowly rising residual currents, ensuring rapid response in everyday household scenarios and effectively preventing potential electric shock risks.

Dual Busbar Wiring for Greater Flexibility:The innovative dual busbar design supports simultaneous wire and busbar connections, offering maximum installation flexibility and convenience. Ideal for quick wiring in residential distribution boards, it significantly reduces installation time and the risk of errors.

Wide Range of Current Ratings and Pole Configurations:Available in rated currents of 16A, 20A, 25A, 32A, 40A, 50A, 63A, 80A, and 100A, with 1P+N or 3P+N pole options. This comprehensive selection meets diverse household needs, from single-phase lighting circuits to three-phase appliance power supplies.

High Sensitivity and Enhanced Safety:Built on the advanced ID technology platform, it offers selectable rated residual operating currents (I△n) of 0.03A, 0.1A, or 0.3A for superior sensitivity. It provides reliable protection against leakage hazards in damp areas such as kitchens and bathrooms. A built-in leakage fault indicator window allows users to visually check status at a glance.

Durable Materials and Robust Structural Design:Internal plastic components are made from high-temperature-resistant materials that resist deformation under temperature fluctuations. The reinforced flame-retardant nylon housing (V2 rating) and premium silver-alloy contacts ensure long-term, stable performance. The operating mechanism features a true free-tripping function, locking only in the fully ON or OFF position to eliminate intermediate-state risks. Its modular design allows seamless integration with an automatic recloser module for intelligent power restoration.

GYL9-AC Type AC RCD Advantages in Residential Applications：

• Everyday Safety Guardian:Specifically tailored for household linear loads (e.g., electric water heaters, chargers, and other sinusoidal AC circuits), it rapidly detects and isolates leakage currents with ultra-fast tripping times: ≤0.1 s at I△n, ≤0.08 s at 2I△n, and ≤0.04 s at 5I△n—effectively preventing electric shock accidents.
• Easy Installation and Operation:Compact design (only 36 mm wide for 1P+N, 72 mm for 3P+N) allows seamless integration into standard home distribution boards. With a tightening torque of 2.5 N·m and wiring capacity of 1–35 mm², installation is quick and tool-free, requiring no professional expertise.
• Reliable, Durable, and Low-Maintenance:High rated short-circuit withstand capacity (Inc/I△c up to 6000 A or 10,000 A) prevents explosion or fire during short-circuit events, eliminating secondary hazards. High-temperature-resistant and flame-retardant materials minimize fire risks, extend service life, and significantly reduce maintenance costs.
• Smart Indication and Expandability:The built-in leakage fault indicator clearly shows whether a trip was caused by residual current, simplifying troubleshooting. Fully compatible with smart home systems and optional recloser modules, it enables automatic power restoration after faults, enhancing convenience and quality of life.
