Description ▲

Is applicable to devices for surge protection of telecommunications and signalling networks against indirect and direct effects of lithning or other transient overvoltages. The purpose of these SPDs is to protect modern electronic equipment connected to telecommunications and signalling networks with nominal system voltags up to 1 000 V (r.m.s.) a.c. and 1 500 V d.c.
