Our SIRIUS contactor range offers everything for switching industrial loads: Contactors and ready-to-use contactor assemblies for switching motors and special applications.

Various different switching devices are available for switching electrical loads. The contactor is the ideal device for performing switching operations which are frequently repeated; it is the most commonly used switching device in industry, mechanical engineering, and the manufacture of switching stations.

All SIRIUS 3RT2 motor contactors (with at least 1 NC contact) are tested to EN 60947-4-1 and have featured mirror contact characteristics in conjunction with auxiliary switches ever since the product was launched.

Features of The SIRIUS contactor range with a width of 45 mm (size S00/S0) comprises:

3RT20 power contactors for switching motors of up to 18.5 kW/400 V (AC-3) and resistive Loads of up to 50 A (AC-1)

3RH2 contactor relays for switching in the control circuit with contact versions of 4 NO contacts, 3 NO contacts + 1 NC contact, and 2 NO contacts + 2 NC contacts

3RA23 (reversing) and 3RA24 (star-delta (wye-delta)) contactor assemblies
