HQ46 Cable type 500A mv output AC clamp on current probe

mv AC clamp on current probe

The HQ46 AC Current Probe is designed for easy installed in tight spaces and without the need for dismantling the primary busbar or cables. The sensing head uses sliding push-fit clamp structure, safety isolation to avoid the user to contact with charged objects directly. It complies with CE standards and meets 600V CAT III safety class..
