Core advantages of the product

safety protection

The wiring terminal is designed to prevent finger contact, with overvoltage category III and pollution level 3, reducing the risk of electric shock.

The residual current protection device covers an operating current of 10mA-500mA, balancing personal safety and fire prevention.

Some products have a maximum surge current resistance of 3kA, while the NEB/HEB series can withstand high short-circuit currents.

Operation and Installation

The sliding buckle design realizes tool free disassembly and assembly, and the assembly of 5SY series accessories does not require additional tools.

The window design intuitively displays the on/off status (red=powered on, green=disconnected), and the ergonomic anti slip handle is easy to operate.

Up and down incoming lines are optional (DC type according to polarity), dual terminals support dual strand wiring, and busbars simplify wiring.

Adaptability and reliability

The pole number covers 1P-4P and 1P+N/3P+N, and the trip curve B/C/D type is suitable for different loads (lighting/motors/industrial equipment).

Storage temperature -40 ℃~+75 ℃, ambient temperature -25 ℃~+55 ℃, suitable for harsh environments.

The maximum mechanical lifespan is 20000 cycles, and the maximum electrical lifespan is 10000 cycles, ensuring long-term stable operation.
