Description
Continuous starting, reducing current peaks, avoiding mains voltage fluctuations during startup, relieving the load on the power supply network, reducing the mechanical load in the drive, considerable space and wiring savings compared to star-delta starters and frequency converters, maintenance-free switching and simple handling. The integrated bypass allows for a very compact design and reduces heating in the control cabinet. Worldwide approvals (e.g. IEC and UL/CSA).
The 3RW soft starters are available for networks up to 690 V in a large power range with different control supply voltages and continuously with screw and spring-type terminals. With 3RW30/40 there are additional variants with 24 V control supply voltage. Some of the 3RW40 up to size S3 as well as all 3RW44 also offer a thermistor motor protection.
With the optional connection module, the soft starters can be attached to the circuit breakers, even for the versions with spring-type terminals.
Simple, efficient, always up-to-date - the SIRIUS modular system.
