Due to two-phase control, the current is kept at minimum values in all three phases throughout the entire starting time and disturbing direct current components are eliminated in addition. Applicable in an enclosure with minimum overall manuall of by by mm.

Actual start times are load dependent. More about lead time. S3 Covers for soft starters Terminal covers for box terminals Additional touch protection to be fitted at the box terminals 2 units required per device 3RW40 3. With its 3rw40056-6bb44 components, the SIRIUS modular system covers maual functions for control cabinet applications and offers numerous advantages in terms of assembly and handling, application monitoring, connection to the control as well as planning and 3rw4056-6bb44.


The set values depend on the application in question and must be optimized during commissioning. How to get the instrument calibrated? Reduce paperwork and access all invoices in one place using My Account. Function Equipped with modern, ergonomic user prompting the SIRIUS 3RW44 soft starters can be commissioned quickly and easily using a keypad and a menu-prompted, multi-line graphic display with background lighting. The 3RR2 monitoring relay is to be enabled via an upstream timing relay after soft start-up completion.

At the same time the acoustic quality of the starting operation comes close to the quality of a threephase controlled soft starter. Furthermore, compact electrical cabinets can be configured with high packing densities. S00 3RVAA00 7 3 8 1 1 2 manuxl 2 6 3 3-phase busbars with infeed on the left incl. During operation and when control voltage is applied, the display field continuously presents measured values and operating values as well as warnings and fault messages.
