Siemens SIRIUS 3RV2 Series – Motor Starter & Circuit Breaker Protectors:

3RV2 motor starter protectors are compact current-limiting devices which have been optimized for load feeders. They are used for protecting and switching three-phase motors and other loads. The scalable setting ranges mean that a suitable motor starter protector can provide protection for all standard motors at ambient temperatures of ≤ 60 °C. 3RV2 motor starter protectors are uniformly fitted with rotary operating mechanisms.

The motor starter protectors are available with the following connection system options (in the main circuit) :

  • Screw-type connection system (up to 80 A)
  • Spring-loaded connection system (3RV2 only, in sizes S00 and S0 up to 32 A)
  • Ring cable lug connection system (3RV2 only, in sizes S00 and S0 up to 32 A)

    Series Features:
  • Circuit-breaker for motor protection
  • Screw connection/ Spring clamp
  • Class 10
  • Impulse voltage resistance 6 kV
  • Insulation voltage 690V
  • Real loss power only 6/7W
  • Standard switching capacity
  • Approvals: CE / UL / CSA
  • Up to 20 % less power consumption than previous solutions
  • Three-phase motors up to 37 kW at 400 V AC
  • Loads with rated currents of up to 80 A
  • Compatible for use in all infeed systems (3-phase busbars, 3RA62), 3RV29 infeed2), 8US)
  • Reduced temperature rise in the control cabinet
  • Cost savings during operation
  • Motor starter protector combined with undervoltage release and contactor can be used as a Cat. 3 feeder in accordance with EN 951-1, SIL 2 in accordance with IEC 62061 or PL d 13849-1
  • 3RV2 motor starter protectors meet the requirements for motor and system protection according to IEC 60947-2 / DIN VDE 0660-101

    Motor and system protection is achieved using the following functions:
  • Overload protection
  • Short-circuit protection
  • Phase loss sensitivity

  • Short-circuit protection
  • Motor protection (also with overload relay function)
  • System protection
  • Short-circuit protection for starter combinations
  • Transformer protection
  • As main and EMERGENCY OFF switches
  • Use in IT systems
  • Switching direct current
  • Hazardous areas (ATEX)
  • Use as Branch Circuit Protection Device (BCPD) according to UL (3RV27/28)
