Voltage Protection Relay

Voltage Protection Relay


Novatek India Enterprises offers single-phase Voltage Protection Relays, RN-111M. These are used for the protection of single-phase loads, equipment and machinery against un-allowable mains voltage drops and fluctuations as well as against the consequences of neutral line cut-off. They can be utilised either as independent switching devices, or as relays operating with a magnetic starter (contactor). Advantages of the relays are wide voltage operation range and broad range of adjustable parameters, including autoreclosing time delay settings for the protection of machinery and installations with long-term transient dynamics, like refrigeration and compressor units.

  • The newest modification of a panel board mounted single phase voltage protection relay.
  • Besides the principal dedication of protecting load against voltage surges in the mains, it provides a number of additional functions – multifunctional digital display, operation mode selection by dipswitch.
  • The relay incorporates functions of 5 complete devices in one compact case – combined over/under voltage protection relay with separate setting of minimal and maximal thresholds.
  • Minimum voltage protection relay, maximum voltage protection relay, protection from the consequences of neutral phase loss; time-delay – auto reclosing after the fault with user defined time delay (protection from frequent starts or nuisance tripping) .
  • Compact overall dimensions – 2-ways width casing.
