Core Product Advantages and Features
Suitable for 7.5kW medium-sized motors
With a rated current of 16A and a power of 7.5kW, it can accommodate a larger capacity three-phase motor compared to smaller models in the same series.
24V AC coil standard
The control voltage is 24V AC (50/60Hz), which is one of the most common safety control voltages in industrial control sites, and spare parts management is convenient.
Screw terminal secure wiring
The main circuit adopts a screw terminal design, ensuring secure and reliable wiring, making it suitable for long-term operation in industrial environments.
S00 body saves tray space
Maintaining the compact size of the S00 facilitates component configuration planning within the limited space of the distribution box.
