The Circutor SEC72 3000/5A Scale (code M102YU) is an exchangeable display scale for EC72 moving iron ammeters. It carries a 3000/5 A full-scale marking, pairing with a 3000/5 A current transformer secondary to indicate primary current up to 3000 A on the panel instrument face. The scale fits the 72 72 mm EC72 ammeter housing and measures 60 60 1 mm.

Technical specifications:

• Model: SEC72 3000/5A Scale
