The DS150E is a Heavy Duty Type 1 AC Surge Protector Device (SPD) designed to be connected at the entrance of the electrical installation. This SPD provides an efficient protection against direct and indirect effects and is particularly useful in a high lightning density area where the risk of heavy surge current or even direct strike is high (e.g. : buildings equipped with lightning rods).
  • The DS150E is a one-pole SPD and can be used in common mode (DS150Es connected between L/PE and N/PE) or common and differential mode (DS150Es connected between L/N and 1 x DS100EG between N/PE).
  • This SPD is designed to withstand a 15 kA lightning current (10/350μs impulse). It is based on «multi-MOV» diagram : this technology allows a very discharge capability and the best behaviour possible on AC network (no follow current).
  • To meet standards, the DS150E includes a thermal disconnection mechanism, fault indicator and an internal microswitch for remote signaling.
  • The SPD is DIN rail compatible and is featured with a double terminal for line wire to allow improved connection to the AC network.

INSTALLATION

DS150E-400 Type 1+2 AC surge protector - 1 pole is 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).

  • Combine two DS150E-400 to get DS152E-400 used for AC 230 V single phase network, IT-TT system
  • Combine three DS150E-400 to get DS153E-400 used for AC 230/400V 3-phase network, IT-TT system
  • Combine four DS150E-400 to get DS154E-400 used for AC 230/400V 3-phase+N network, IT system
