Cylindrical fuse link SRF SRF 20 002636005

Application - SRF 10 cylindrical fuses - special are designed to protect circuits of class C surge arresters (e.g. ETITEC C  275/5 or ETITEC C 275/20) against short-circuit current. These fuses are connected in series with surge arresters. They are characterized by very strong short-circuit current limitation. SRF 10 fuses do not react (do not work) to 8/20μs pulses of discharge current transmitted by surge arresters.

Advantages:
→ strong short-circuit current limitation,
→ rated short circuit capacity -200kA,
→ effective protection of surge arrester circuits against short-circuit current.
