Description
Contactor assembly for star-delta (wye-delta) start AC-3, 15/18.5 kW/400 V, 24 V DC 3-pole, Size S0 screw terminal electrical and mechanical interlock 3 NO + 3 NC integrated Contactor assembly for star-delta (wye-delta) start SIRIUS 3RA24 for the soft starting of three-phase asynchronous motors.
The 3RA24 contactor assembly for star-delta (wye-delta) starting is a proven and factory-fitted combination of three 3RT2 contactors which are already fully wired and interlocked both mechanically and electrically. The function module with integrated control logic and time setting, which is also included, replaces the complete wiring in the control circuit. They are climate-resistant, approved for worldwide use (e.g. IEC and UL/CSA) and are IE3/IE4-ready.
The 3RA24 contactor assemblies for star-delta (wye-delta) starting are available with AC and DC operation in sizes S00 to S3. They are offered with screwor spring-loaded terminals for mounting on DIN rails or screw mounting. Furthermore, versions are available for connection to IO-Link or AS-Interface.
The accessories of the 3RT2 contactors are standard for all sizes and can also be used for the contactor assemblies.
The 3RA24 contactor assemblies for star-delta (wye-delta) starting will succeed the proven 3RA14 series.
Simple, efficient and always up to date - SIRIUS modular system.
