* Type test (DNV is type approved as of April 2006)

Notes:

  • RVS-DN 8 through RVS-DN 820 are UL & cUL and SCCR Approved (does not apply to RVS-DN-AG, SCCR applies to slim version )
  • RVS-DN 1100 and above are designed to meet UL & cUL requirements
  • Contact us for RVS-DN 210, 310, 390, 460, 580, 820 & 950 Slim version (Narrow)
  • Select the starter according to motor's Full Load Ampere (FLA) - as indicated on its nameplate (even if the motor is not fully loaded)
  • The selection table above, concerns standard, 1500 R.P.M. 50Hz, three-phase asynchronous motors. These values are given for guidance and may vary according to individual motor manufacturers (as well as number of poles)
  • It is the user's responsibility to verify that motor's FLA does not exceed Starter's FLC
