Main tolerances:

Total common error:    ±0.5mm

Install:   Vertical position       4 holes φ4.2mm 和2 holes  φ5.3mm

Horizontal position       4 holes  φ5.3mm

Primary aperture: 40.5mm*38.5mm


Remarks

1.IS is positive when IP flows in the arrow direction.

2.Primary conductor temperature should not exceed 100℃;

3.The dynamic performance (di/dt and response time) is the best when the busbar is fully filled with primary perforations;

4.In order to achieve the best magnetic coupling, the primary turns should be wound around the top of the sensor;

5.Products can be customized according to customer requirements.
