Product presentation

The SH 77 range with blade connection for busbars allows a direct current of 600 to 4000 A to be measured, offering a good trade-off between accuracy and size, and its large connection surface facilitates heat dissipation.

Available in class 0.5 and 0.2 with a voltage drop of 100 mV, our range complies with the NFC 42-151/152/153 standards.

A wide choice of class, voltage drop and rating adaptations is available on request
