AC and voltage meters M42300, M42301, M42303, M42304, M42305, M42306, M4264М, M4265М

This group of meters is intended to measure current and voltage in electric DC circuits. These meters allow current measuring within 10 µА...20 А and voltage 25 mV...750 V with their direct switching on.
Meters М42300, М42301, М42304, М42305 can be manufactured with advanced resistance to mechanical effects. When ordering, the letter (m) is added to meter designations. Meters М42300, М42303 can withstand seismic effects equivalent to the vibration effects with acceleration in the range of 1.3...15 m/s2 at frequency of 5...50 Hz in two positions.
Meters М42303 with maximum measurement ranges of 0.5 mA, 20 V and all multirange devices are manufactured with accuracy class 4 only. Meters with advanced protection may be produced under an individual order. Housings design provides IP50 or IP54 protection level for the front frame, IP00 – for live parts. Calibrated wires connecting meters with shunts are included in the set of meters delivery. The DC meters may be manufactured with the origin- and central-zero scale. Meter scales can be made with any units of measurement, special marks, inscriptions, etc. as per Customers data. The standard meters position is vertical or horizontal. Taking into account the order, the meters may be manufactured with other measurement limits.
To protect against contact with current-carrying rods, meters М42300, М42304, М4264М, М4265М may be supplied with protective caps KZ-4. The need of supply shall be specified in case of order.
