Product Details
Siemens Soft Starter, 480V AC, 18.5kW - 3RW40 Series - 3RW4028-1BB14
Use this electromechanical soft starter from Siemens to safely start and stop your industrial asynchronous motors. It regulates the amount of voltage running through a motor's circuits, resulting in a more controlled ramp-up and ramp-down to minimise motor damage. This component features an intelligent monitoring system that protects it and the connected motor from overheating and overload for increased performance and productivity. It also has an integrated remote reset system that lets you quickly and easily clear faults without the need to directly access the device. For ease of installation and maintenance, it's supplied as a modular system that you can easily piece together and dismantle. This device has compact dimensions of 125 (length) x 45 (width) x 154mm (depth), so it's suitable for use in areas where space is limited.
Power rating of 18.5kW for use in heavy-duty motor applications
Link module to connect to circuit breakers for enhanced electrical safety
Wide operating temperature range of -25°C to +60°C for use in harsh environments
Adjustable current limitation system to regulate different motor variants for added versatility
