Siemens Soft Starter, 600V AC Insulation Voltage, IP20 Rating - SIRIUS Series - 3RW4038-1BB14
Choose this soft starter from Siemens to reduce torque and minimise the risk of power surges when starting up your AC motors. You can tailor the device to suit your application as the controls on the front let you limit the current allowed during start-up to a specific value. An IP20 rating means it's touch-proof and resistant to objects larger than 12mm, making it useful for many standard motor control tasks. The remote reset facility gives you control over the device from a distance, so you can clear faults quickly to avoid system downtime.
Features & Benefits
• Rated insulation voltage of 600V means it provides protection against moderate surges
• Can be installed up to 5000m above sea level for compatibility with high-altitude locations
• LED display shows operating parameters for easy status monitoring
• Integrated bypass feature keeps the unit small and supports heat dissipation for safety in your control cabinet
What temperatures can I use this soft starter in?
This soft starter suits an ambient temperature range between -25°C and +60°C, so it's compatible with harsh environments.
