HDT/6/24-F0,25

Article number: 56 100
  • Combined two-stage surge protectors intended for a low voltage data and power supply lines routed by a common cable.
  • Contains both 1st and 2nd stage of protection.
  • The overcurrent protection of the power supply line is ensured by a PPTC resettable fuse.
  • To reset the PPTC, the circuit must be switched off and let the fuse cool down, do not have to be changed.
  • The protection devices must be installed just in front of the protected device.
