Snap-on measuring instruments are used primarily for measuring power current variables in distribution boards. They can be snapped onto 35 mm DIN rails.
The measuring instruments are manufactured in accordance with the requirements of DIN EN 60051 and those of other applicable VDE and DIN guidelines.
Alternating current, alternating voltage, direct current, direct voltage and operating hours can be measured. Accuracy is 1.5% in relation to the upper limit of effective range.
Standard moving-iron ammeters feature a 200% overload scale. All measuring instruments can be continuously overloaded at 120%. Ammeters can be overloaded for short periods of time at up to 1000%, voltmeters up to 200%.
The housing dimensions meet the requirements of DIN 43880 for built-in equipment.
The instruments can also be supplied for mounting on vertical DIN rails.
