SIT Range
The SIT 3 phase contactor is a zero cross relay which includes a built-in heatsink for optimum current switching capability. These units are DIN rail mounted and rated up to 22 amps. Designed for resistive loads or motor control, the device features an integral LED indicator and RC and VDR protection.
This 3 phase contactor has an integral heatsink and is suitable for either resistive loads (AC-51) or motor applications (AC-53). It is built using TMS technology for longevity and has high immunity from electrical noise, making it a good choice for industrial applications.
