3RW4026-1BB04 SIRIUS soft starter, 25 A, 11 kW / 400 V.

The SIRIUS 3RW40 Basic Performance soft starters are suitable for gentle starting and stopping of three-phase asynchronous motors.

The two-phase control not only keeps the current at the lowest values in all three phases during the entire ramp-up time, but also eliminates interfering DC components. This not only enables two-phase starting of motors up to 55 kW (at 400 V), but also avoids the current and torque peaks that occur with star-delta starters, for example.

The SIRIUS 3RW40 soft starters are suitable for starting explosion-protected motors with the "increased safety" EEx e type of protection in accordance with ATEX Directive 94/9/EC.
