• Pointed clip jaws for easier access with dense cable arrays
• Safety in accordance with IEC 61010-1 and IEC 61010-2-032
• Minimal transformation error
• Suitable for use with power meters thanks to minimal phase angle error (exception: WZ12A)
• Compact, handy design

Clip-on current sensors are equipped with a top-quality metal core which reduces eddy-current loss and allows for accurate measuring results even with the low primary current. Damping diodes integrated into the measurement output of the current transformers (with current output) protect the secondary side against overvoltages which occur if the measuring circuit is interrupted, or if the measuring instrument has not been connected. This function is performed by internal load resistors for the current sensor models (with voltage output).

WZ11 current clips are physically somewhat larger than WZ12 series devices, but they offer a larger spectrum of current measuring ranges and a higher voltage category.
