Lider Single Phase Preventer With Auto Restart-(Auto switch) Transformerless

L-ASWT

  • For safe running of 3-phase equipments, special protection devices are required to keep a continuous watch on supply
  • The major cause of maximum 3-phase equipments burn-out is overloading which occurs due to unbalance supply or single phasing. Phase failure occurs in case of loose connections, fuse blown-off or loss of phase from supply itself. Protection to 3 phase equipments against single phasing, reverse phasing or unbalance voltage supply is one of the major problems in electrical

Product Description

PRODUCT DESCRIPTION/FEATURES

  • Our LIDER Single Phase Preventer with Auto Restart (AUTO SWITCH) gives these protections along with HIGH/LOW voltage tripping to ensure trouble free running of 3 Phase equipments and it auto starts the equipment with ON DELAY time of 30 secs.
  • Our LIDER Single Phase Preventer with Auto Restart (AUTO SWITCH) gives ON indication by LED after DELAY time of 30 secs under healthy voltage conditions and during phase failure, reverse phasing or phase unbalance (40V +-6 V, Fixed) indication becomes OFF.
