Description

The 52 Series CAT IV 600V AC Current Clamp-On Probes are a high performance current sensor incorporating a split iron core window current transformer with low ratio and phase errors, specifically designed as an accessory for CHK Power Quality instruments used on energised circuits and in CAT IV environments.

The 52 series is suitable to use outdoors in wet and humid environments.

Tactile barriers are included on either side of the body handle and provide clearance to prevent the operator from contacting hazardous live voltages. Protective shrouds attached to the ends of the jaw openings also prevent the iron core from contacting hazardous live cables during application and removal of the clamp.
