Core Product Advantages and Features
24VDC coil
It can be directly driven by DC power supply or PLC output, and is suitable for situations where the control circuit is powered by DC.
AC-3 rated 51A, 22kW
A 22kW three-phase motor can be directly started at 400V, and the 690V rated insulation voltage ensures withstand voltage margin.
1NO+1NC auxiliary contact
It has one set of normally open and one set of normally closed circuits built in, which facilitates feedback of motor operating status and interlock control.
Size S2 Main Circuit Screw Terminal
The 3-pole main contacts are fixed with screws, making wiring construction, maintenance and repair convenient.
