Owing to a special form and available colours, BN and CN meters are especially convenient for building into different control devices. The accuracy class is 1.5. The scale is not interchangeable. BN meters are used for DC currents or voltages, CN for AC currents or voltages.
Meters are available with different front frames:
BN 0103 – 86 x 72 mm
BN 0203 – 115 x 96 mm
CN 0103 – 86 x 72 mm
CN 0203 – 115 x 96 mm
They have a round cutting for mounting with diameter 65 mm.
