The Circutor SEC72 20/5 A (code M102Y5) is an exchangeable replacement scale for the EC72 series moving iron ammeter. Printed for a 20/5 A measurement range, this dial face allows the EC72 instrument to display primary current up to 20 A when paired with a current transformer having a 5 A secondary output. The scale measures 60 x 60 x 1 mm and fits the 72 x 72 mm panel module format of the EC72 ammeter.
