Bimetallic Ammeter BA27, 480A 400/5A, cl.3, 15min, scale 90°, ■72x72mm/ □68x68mm, Lumel

Bimetallic Ammeters with maximal current indicator combined bimmetallic and moving-iron ammeters with maximal current indicator

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.
