SPD Class B, Lightning Current Arrester SPI

• Field of application: For the protection of low voltage distribution systems

against direct lightning stroke into the overhead power supply line or exter-

nal lightning protection system (IEC 62305).

• Application according to IEC 60364-5-53 Clause 534

• Test class

in accordance with IEC 61643-1

• SPD-type

in accordance with EN 61643-1

• Capsuled version: during the discharge process, the device does not issue

any hot ionised gases. Therefore, there is no need for keeping a safety dis-

tance to flammable materials.

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.

Practical Hint

Application Example

Attention!

SPI-.../NPE should be used only as a

N-PE spark gap in a e.g. TT-system (con-

nection type 2 according to IEC 60364-5-

534 Clause 534)
