Siemens SIRIUS 3RT2 Contactors
Siemens SIRIUS 3RT2 power contactors for switching motors and other loads, sizes S00 to S2, with AC or DC coils.
Overview
The 3RT2 is Siemens's current range of SIRIUS power contactors. The order number sets the size (S00, S0, S2), the rated current and the coil voltage, so a replacement has to match all three. The units listed here run from 7 A (3 kW at 400 V, size S00) to 51 A (22 kW at 400 V, size S2), with 24 V DC or 110 V AC coils and built-in auxiliary contacts. They pair with SIRIUS 3RV2 motor protection circuit breakers of the same size to make a motor starter. TIMC quotes new and surplus 3RT2 contactors against the order number on the unit.
Availability, condition and lead time confirmed on enquiry.
