Abstract
What is BS EN IEC 61643 ‑ 331 about ?
BS EN IEC 61643 ‑ 331 is the 331st of components for low-voltage surge protection in multi-series.
BS EN IEC 61643 ‑ 331 is a test specification for metal oxide varistors (MOV), which are used for applications up to 1 000 V AC or 1 500 V DC in power lines, telecommunication, or signalling circuits. They are designed to protect apparatus or personnel, or both, from high transient voltages. <...
