Surge Protection Device

• Field of application: For the protection of low voltage distribution systems against direct lightning strike into the overhead power supply line or external lightning protection system (IEC 62305)
• Application according to IEC 60364-5-53 Clause 534
• Test class I, II, III in accordance with IEC 61643-1
• SPD-type T1, T2, resp. T3 in accordance with EN 61643-1
• Lightning protection classes III and IV in accordance with IEC 62305
• Capsuled version: during the discharge process, the device does not issue any hot ionised gases.Therefore, there is no need for maintaining a safety distance from flammable materials.
• Depending on application available in single, pre-assembled with busbar, or preconfigured for most applications and power grids

Installation of lightning current arresters upstream of the meter is subject to co-ordination with the relevant power supply company. Installation of an r.m.s.ective protection cascade (SPD classes B, C, D) requires co-ordinated application of the respective protective devices. This is ensured by a defined line length between protective devices. When using lightning current arresters of type SPI in connection with surge arresters SPC with a maximum continuous operating voltage Uc of 460 V AC, no specific line length or decoupling coils are required.
