The PowerSure DRS is a Modular Surge Protective Device (SPD) that is designed for easy installation in existing AC panelboards and control panels using standard DIN rail mounting brackets. The PowerSure DRS devices offer both normal and common surge protection up to 40 kA per phase.
Features
  • Built-in thermal components disconnect  SPD from the power source to avoid thermal runaway conditions
  • MOV only or MOV+Gas Tube models available
  • Fast response time, high surge current capability, low voltage protection levels
  • Visual inspection window on each module indicates status
  • 5 year warranty
Benefits
  • Effectively handles high-energy transients on TT, TN-C, TN-S and TN-C-S three-phase power systems
  • SPD rated Type 2 in accordance with EN 61643-11; Class I & II in accordance with IEC 61643-1
  • 3-pole terminal provides remote status monitoring
  • DIN rail mounting and plug-in module design allow for easy installation, maintenance and replacement of surge element
