  • Brand / Made in
    CITEL / FRANCE
  • DC or PV power surge protector
  • 110 Vdc
  • Compact design
  • Imax: 40 kA
  • Pluggable module
  • Remote signaling (option)
  • Very low Up protection level
DS210-DC surge protectors are designed to protect equipment connected to DC (and AC) power supplies from lightning surges. It is based on varistors matched to the network voltage: the varistors have thermal disconnection devices to control any end-of-life. These SPD are DIN rail compatible and is connected in parallel on the line to be protected.

Installation

DS240-110DC surge protectors are connected in parallel on the DC network and must be equipped with external fuses for short-circuit current protection

  • The total length of parallel connection wires to DC network must be lower than 0.5 m in order not to increase the protection level (Up) provided by the SPD.
  • Wiring is made by screw connections. On some models, a distribution bus can be used.
  • The protection wire coming from the SPD must be connected to the bonding bar of the electrical panel. Paralleling the protection wire with phases conductors must be avoided.
  • Local earthing resistance must be in compliance with the electrical rules.
