3RW4047-1BB05, soft starter S3, 106A, 75kW / 500V, 40 degrees, AC400-600V, AC / DC24V

Gentle starter S3, 106A, 75kW / 500V, 40 degrees, AC400-600V, AC / DC24V

SIRIUS Soft starter S3 106 A, 75 kW / 500 V, 40 ° C AC 400-600 V, AC / DC 24 V SIRIUS 3RW40 screw clamps for standard applications for the gentle start and output of rotary current synchronous motors. Sturdy start-up, reduction of current points, avoidance of current voltage fluctuations in the run-up, relief of the power supply network, reduction of mechanical load in the drive, significant space and wiring savings compared to star triangular starters and frequency converters, maintenance-free switching and easy handling. The integrated bypass allows the very compact design and ensures a lower heating in the control cabinet. Intelligent monitoring functions protect the soft starter from overheating and the engine from overload. You can also limit the current to an adjustable maximum value during the high run. With the integrated remote reset, you can quickly and easily fix problems from a distance. Worldwide approvals (e.g. IEC and UL / CSA) also for potentially explosive applications (ATEX or IEC Ex). The soft starter 3RW is available for networks up to 690 V in a large power range with different control power supply voltage and continuous with screw and spring connection. With 3RW30 / 40 there are additional variants with 24 V control power supply. Some of the 3RW40 to size S3 as well as all 3RW44 also offer a thermistor motor protection. With the optional connection component, the soft starter can be mounted to the circuit breakers, even for the variants with spring connection. The optional fan allows even more dense construction in the control cabinet. Simple, efficient, always up to date - the SIRIUS system kit.
