Core advantages of the product

safety protection

Dustproof and finger touch resistant design: Insulation protection for wiring terminals to reduce the risk of electric shock.

High current limit level: Level 3 energy limit, maximum breaking capacity of 10kA, quickly cutting off fault current.

Multiple protection types: residual current protection (AC/A type), overvoltage and undervoltage protection, and full coverage of surge protection.

Installation and Operation

Sliding buckle design: tool free installation and disassembly, improving construction efficiency.

Compact design: 18mm modular structure, compact product with only 1 module width, saving distribution box space.

Flexible adaptation: Up and down incoming lines are optional, and can be installed in any position to meet different wiring requirements.

Energy saving and durability

Low power consumption: The measured power consumption is 1/3-1/2 of the standard definition, and the energy-saving effect is significant.

Long lifespan: Mechanical lifespan up to 20000 cycles, electrical lifespan up to 10000 cycles, suitable for frequent operation.

Environmental adaptation: working temperature -25 ℃~45 ℃, storage temperature -40 ℃~75 ℃, supporting high-altitude environment (within 5000m altitude).
