Remarks:
1. All dimensions are in mm.
2. General tolerance ±1mm
Directions for use
Is will be in a forward direction when the Ip flows according to the direction of the arrowhead.
The primary conductor should be≤120℃.
The dynamic performance (di/dt and the response time) is the best when the primary hole is fully filled with the bus bar.
