Meters with 60х60, 80х80 and 120х120 mm front frame

Panel AC and voltage meters are manufactured of two types:
– magnet-moving coil system with rectifier;
– electromagnetic system;
These meters allow current measuring within 25 µА...100 А and voltage 0.5 V...750 V with their direct switching on. To extend a measurement range: by current – current transformers type TOP-0.66 are used, by voltage – voltage transformers.
Ammeters and voltmeters are made with the zero-scale at the range edge. The meters can be made with any scales of any units of measurement according to Customer’s request.
For structural design, the AC meters are divided into two groups:
– meters with square front frames and round cases.
– meters with square front frames and square cases. The protection level for the front frame is IP50 or IP54, protection level for current-carrying rods – IP00.
To protect against contact with current-carrying rods, meters E42700, E42702 (ammeters up to 10 A, milliammeters, voltmeters, meters with actuation via current/voltage transformers), Ts42300, Ts42702 may be supplied with protective caps KZ-4. The need of supply shall be specified in case of order.
