Remarks:
1. All dimensions are in mm.
2. Secondary pin size and tolerance: width:0.5±0.1mm;thickness:0.25±0.05mm
3. General tolerance ±1mm.
| Directions for use |
When the current will be measured goes through the primary pin of a sensor, the current will be measured at
the output end. (Note: The false wiring may result in the damage of the sensor).
Custom design in the different rated input current and the output current are available.
