EA0302/1U ampermeters of electromagnetic system, panel board are intended for measurement of alternating current of a sinusoidal form of frequency from 45 Hz to 65 Hz.
- angular arrangement of a loose port;
- liquid damper of mobile system;
- big length of a scale;
- beginning of range of measurement of 10% of a finite value

|Note 1. Depending on the order ampermeters with a finite value of range of measurement less than 1 And can be produced as milliammeters, and ampermeters with a finite value of range of measurement more than 1000 And|
can be produced as kiloammeters.
Note 2. The measuring current transformer should be with a rated force of secondary winding at 1 A or 5 And.
By the special order ampermeters with other ranges of measurement, and also with special marks, texts and other functional sites of scales can be manufactured.
Accuracy rating of devices - 1, 5; 2, 5 in accordance with GOST 8711.
Leading dimensions of devices of 120 mm x 120 mm x 78 mm.
