Features:

  • Space-saving ECB with four channels
  • 0.5–6 A nominal current, adjustable for each channel via sealable selector switch
  • Active current limitation
  • Switch-on capacity > 65000 μF per channel
  • One illuminated, three-colored button per channel simplifies switching (on/off), resetting, and on-site diagnostics
  • Time-delayed switching of channels
  • Tripped message (group signal)
  • Status message for each channel via pulse sequence
  • Remote input resets tripped channels or switches on/off any number of channels via pulse sequence
