Analog ammeter E47 10A accuracy class 1.5 96x96mm IEK IPA20-6-0010-E

Used in low-voltage kit devices in electrical distribution networks of residential, commercial, and industrial facilities. E47 Ammeters are analog electromagnetic electrical measuring instruments designed to measure current in AC electrical circuits. Comply with the requirements of GOST 30012.1, 8711, 22261; GOST R 52319, 51522, 51317.3.2, 51317.3.3 and are manufactured according to technical specifications TU 4223-023-18461115-2008. E47 electrical measuring instruments are entered in the State Register of Measuring Instruments. A type approval certificate for the measuring instruments has been obtained. Principle of operation: E47 ammeters belong to instruments with an electromagnetic system. They consist of a round coil with movable and stationary cores placed inside. When current flows through the coil windings, a magnetic field is created, magnetizing both cores. As a result, like poles of the cores repel each other, and the movable core rotates the needle axis. To protect against the negative influence of external magnetic fields, the coil and cores are protected by a metal shield.
