Selection checklist

  • Continuous current and short-time withstand
  • DC voltage, load type and breaking duty
  • Epoxy sealed EVI vs ceramic sealed EVM
  • Coil voltage, economizer and auxiliary contact
  • Busbar terminal spacing and mounting hole pattern
  • Application: EV, ESS, PV inverter, DC charger
