Abstract

What is BS EN IEC 62271 ‑ 104 about?

BS EN IEC 62271 ‑ 104 discusses about high-voltage switchgear and controlgear. BS EN IEC 62271 ‑ 104 is applicable to three-pole alternating current switches for rated voltages higher than 52 kV, having making and breaking current ratings, for indoor and outdoor installations, and for rated frequencies up to and including 60 Hz. BS EN IEC 62271 ‑ 104 is applicable to the operating devices of these switches and to their auxiliary equipment. General purpose switches for this application are designed to comply with the following service applications:

Carrying rated continuous current, carrying short-circuit currents for a specified time
