IEC 61643-22 Testing
Low-voltage surge protective devices – Part 22: Surge protective devices connected to telecommunications and signaling networks – Selection and application principles
IEC 61643-22 Scope:
IEC 61643 22 and EN 61643 22 testing describes the principles for the selection, operation, location and coordination of SPDs connected to telecommunication and signaling networks with nominal system voltages up to 1000 V r.m.s. A.C. and 1500 V D.C. This standard also addresses SPDs that incorporate protection for signaling lines and power lines in the same enclosure (so called multiservice SPDs).
