CITEL DS240-230/G

The DS240 Type 2 surge protectors are compact devices designed to protect single phase networks at the main switchboard. They provide a common or common / differential mode protection.

This SPD is based on high energy varistor equipped with thermal disconnectors and failure indicator to comply with standards. The DS240 is DIN rail compatible and is built with a plug-in module and fixed base, which allows an easy and fast maintenance.

Remote signaling of disconnection: option DS240S-230/G : output on changeover contact

INSTALLATION

DS240-230/G Type 2 AC surge protector - single phase are connected in parallel on the AC network and must be equipped with external fuses for short-circuit current protection

  • The total length of parallel connection wires to AC 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.
  • The cross sectional wire must be 6 mm² minimum for Type 2 SPD and 16 mm² for Type 1.
  • Local earthing resistance must be in compliance with the electrical rules.

Further information can be found in IEC 61643-12 standard (selection and application principles for low voltage SPD).
