Siemens 3RW4056-6BB45 Soft starter SIRIUS 3RW40

SIRIUS soft starter S6 162 A

Soft starters 250 kW are appropriate for standard 3-phase applications and are designed for soft on/off of 3-phase asynchronous motors. They prevent the inrush current and torque that happen when utilization star-delta starters. The Sirius 3RW40 is organized with optimum operating. The built-in bypass contact system diminishing energy losses during working, so the components element does not warm-up. With the 4-step rotary switch, the overload trip time may be install. Full managed amperage limit, the motor is surely protected even from a surprise growth in current strength. Three LEDs are utilized to mapping the possible errors, ineffective trip times (trip class), phase failure, device failure. The main typical applications: construction machines, presses, escalators, chillers, working mechanisms, mixers.
