Core Product Advantages and Features

S0 frame compact design

Adopting the SIRIUS 3RV2 series S0 frame, its compact design facilitates panel configuration and is suitable for small and medium-sized motor control circuits.

Screw terminal wiring

The main circuit uses screw-type terminals, which can lock 1~10mm² wires, making maintenance wiring and on-site construction convenient.

35mm standard guide rail installation

Supports screw fixing or direct snap-fit to 35mm DIN standard rails, ensuring quick and secure installation.

Three-pole overload and short circuit protection

The three-pole main circuit design features dual protection mechanisms: thermal overload and magnetic instantaneous short circuit tripping.
