FRER 1TAC022200-05 is a current transformer (CT) of type AC22 designed for high‑voltage current measurement and protection. It delivers a 200:5 (40:1) current ratio and is available with burden ratings of 5, 10, or 12 VA to suit different relay or metering inputs. Its insulation rating between primary and secondary is 0.72–3 kV, making it suitable for installations within that voltage class while providing a standard secondary current for monitoring.
