Connection
Mechanical characteristics
* General tolerance * Transducer fastening
Recommended fastening torque * Primary through-hole * Connection of secondary Recommended fastening torque 1 mm 4 holes 11 mm 4 x M10 steel screws 11.4 Nm or 8.48 Lb - Ft 200 mm M5 threaded studs 2.2 Nm or 1.62 Lb - Ft
Remarks
* IS is positive when IP flows in the direction of the arrow. * Temperature of the primary conductor should not exceed
100C.
* Dynamic performances (di/dt and response time) are best
with a primary bar in the center of the through-hole.
* This is a standard model. For different versions (supply
voltages, turns ratios, unidirectional measurements...), please contact us.
LEM reserves the right to carry out modifications on its transducers, in order to improve them, without previous notice.
