• Temperature of the primary conductor should not exceed

100°C.

• Dynamic performances (di/dt and response time) are best

with a single bar completely filling the primary hole.

• In order to achieve the best magnetic coupling, the primary

windings have to be wound over the top edge of the device.

• To measure nominal currents of less than 50 A, the optimum

accuracy is obtained by having several primary turns (nomi-

nal current x number of turns < 50 At).
