Siemens SIRIUS 3RW Soft Starter, , 37 kW, 400 V ac, 3 Phase, IP20

This Siemens soft starter moderates the operating parameters of a motor when it's activated. It does this by gradually inputting current to prevent motor overload. Thanks to a minimum voltage of 200V and a maximum of 480V, along with an ambient temperature range of -40°C to +80°C, you can use this device in a wide variety of applications and environments. The starter uses a NO (normally open) auxiliary contact which keeps the connection in constant operation, allowing for automatic reaction time. Install this soft starter in mechanical kit that uses a heavy motor.

• +40°C derating temperature dissipates heat to prevent overheating
