HQ15 5A 100A High-value voltage output AC current clamp sensor

voltage output current clamp sensor

The HQ15 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 300V CAT III safety class.
