Core Product Advantages and Features

440-480V AC/DC coil

The operating mechanism can be directly driven by a 440-480V AC or DC power supply, making it suitable for high-voltage control power supply applications.

S6 large chassis main circuit

The AC-3 has a rated current of 115A and a power output of 55kW at 400V, meeting the needs of large-scale three-phase power applications.

Standard auxiliary contacts

Built-in 4 sets of instantaneous auxiliary contacts (2NO+2NC), which can be used for interlocking and status feedback.

Dual-terminal type

The main circuit uses square terminals, while the control and auxiliary circuits use screw terminals for easy wiring.

Wide voltage level main circuit

The same series of products can be used in various main circuit voltage applications ranging from 400V to 690V.
