DLA protect I&C, telecommunication equipment and data technology systems from lightning effects and surges. Designed for DIN rail mounting, these surge protectors can be used for all applications with voltages from 6 V to max. 170 V and transmission rates up to 10 Mbit/s and protect one (DLA) to two (DLA2) pairs with a plug-in protection module. The electrical circuit of the DLA consists of a combination of high-performance gas discharge tubes and fast-switching diodes for high discharge capacity and fast response behaviour. The shield connection is additionally earthed via a gas discharge tube. The earthing connection is conveniently made via the top-hat rail. When the plug-in module is unplugged, the transmission signal is not interrupted. Special versions: DLAH are protective devices for applications with higher current values, operating current for connected operating devices up to 2.4 A. DLAW is a version which interrupts the signal transmission when the protection module is pulled out. D3 types aim to realize fine protection and D2 types is specific for floating applicaiton.

Installation

  • DLA-06D3 surge protectors are connected in serial on the network. 
  • The protected equipment must be nearby (protector/equipment distance less than 10 m long). If this rule cannot be followed, «secondary» protection must be installed near the equipment (coordinated surge protection).
  • The total length connection wires to 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. 
  • The protection wire coming from the SPD must be connected to the bonding bar of the electrical panel. 
  • Local earthing resistance must be in compliance with the electrical rules.
