BOQ bi-metal rotary current meter

BOQ bimetal moving-iron ammeter

Combined current meter (bimetal + moving iron) with drag indicator. Robust combined instrument for current measurement via current transformers (secondary 1 A or 5 A), consisting of a bimetal maximum measuring unit with drag indicator and a moving-iron measuring unit for instantaneous value display.

The red slave pointer reliably indicates the maximum thermal value, while the black pointer shows the current instantaneous value. The measurement is temperature-compensated for the application range from -10°C to +55°C.

A sealable reset button allows the drag indicator to be reset manually.

Features:

1. Connection via current transformer (1 A or 5 A secondary)
2. Accuracy classes: 3 (bimetal) and 1.5 (moving iron)
3. Continuous overload: 1.2 × IN
4. Short-time overload: 10 × IN for 1 s (according to DIN 43780)
5. Thermally inert bimetallic measuring mechanism with maximum display
6. Instantaneous value display via moving iron movement
7. Sealable reset button
