Motor Starter / Contactor · Motor Control
The Siemens 3RW40 is a motor starter covered by a DNV certificate. It is installed in motor control centres, starter panels and switchboards to start and protect AC motors on pumps, fans and other auxiliary machinery, and it limits the mechanical and electrical stress of starting compared with direct switching.
Listed in the DNV Approval Finder at the time we recorded it. The certificate is issued by DNV, not by us; check its current status at DNV.
