function module star-delta (wye-delta), consisting of lateral basic module and two coupling modules, time range 0.05-60 s, 24-240 V AC/DC, 50/60 Hz, varistor for attenuation of the contactor coils integrated, for contactors 3RT20 function module SIRIUS 3RA

function module star-delta (wye-delta), consisting of lateral basic module and two coupling modules, time range 0.05-60 s, 24-240 V AC/DC, 50/60 Hz, varistor for attenuation of the contactor coils integrated, for contactors 3RT20 function module SIRIUS 3RA28 for star-delta (wye-delta) starting for mounting on 3RT2 contactors and 3RH2 contactor relays, e.g. for targeted startup of motors, fans and ventilators.Easy assembly without tools of star-delta (wye-delta) starters, including timing function and electrical interlock, without additional wiring. This enables you to avoid wiring errors and to reduce testing costs. The front mounting on the devices saves you space on the DIN rail. No additional protective circuit is necessary. The automatic prioritization circuit reduces current peaks. Thanks to international approvals (e.g. IEC, CCC, UL/CSA), the devices can be used worldwide.The function modules are available for 3RT2 contactors and 3RH2 auxiliary switches in sizes S00 to S3.
