Амперметры с индикатором IMAX и двухдейтивным амперметром

APPLICATION
Bimetallic and combined ammeters are especially intended for thermal monitoring of transformers, cables and other electrical devices which have a slow reaction to current changes.
They indicate the mean rms current value during the measuring period of the meter (8 or 15 min.). These meters do not react to short current pulses essentially. The range of these meters can be enlarged by means of external measuring current transformers which are also offered by LUMEL and can be delivered on request if the meter is ordered in the option enabling a direct assembling on the current transformer.
 

ACCESSORIES

We deliver together with the meter:
- two snap screw holders to fix the meter,
- a protective terminal cover,
- a quality inspection certificate (if ordered).

Categories of climatic versions
If there is not given in the order, meters are destined to be applied in closed rooms, not air conditioned, in conditions of a moderate climate, acc. to EN 60051 standard. On request, meters can be adapted to be used in a dry or wet tropical climate also in closed, not air conditioned rooms. They are then marked by the TIII symbol.
Working temperature range of meters
These meters operate without damage in the temperature range: from -25oC to +40oC, in accordance with the binding standards.
Matching of meter measuring ranges to current transformer ranges:Through the dial exchange. The exchange way is shown in the user,s
manual.
