The Sirius 3RW40 soft starters are characterized by their small footprint. Integrated bypass contacts avoid that power losses on the power semiconductors (thyristors) have to be accepted after the motor has started up. This saves heat loss, allows a more compact design and eliminates the need for external bypass circuits. This soft starter also offers integrated additional functions such as adjustable current limitation, motor overload and internal device protection and optional thermistor motor protection.
The internal device protection prevents the thermal overload of the thyristors and the resulting defects in the power section. Optionally, the thyristors can also be protected against short circuits with semiconductor protection fuses. Thanks to integrated status and error monitoring, this compact soft starter offers a wide range of diagnostic options.Up to four light-emitting diodes and relay outputs allow differentiated observation and diagnosis of the drive by informing about the operating state, e. Mains or phase failure, missing load, impermissible tripping time / class setting, thermal overload or device errors.
Soft starters with an output of up to 250 kW (at 400 V) are available for standard applications in three-phase networks. Smallest designs, low power dissipation and easy commissioning are just three of the numerous advantages of the Sirius 3RW40 soft starter. Rated operational current Ie at 40 ° C Tu.
