| Mechanical dimension(for reference only) |
Remarks:
1. All dimensions are in mm.
2. General tolerance ±1mm.
| Directions for use |
When measure current flows according to the direction of the arrowhead, Output terminal gets the same phase current.
When the current will be measured goes through 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.,
