Fluke 1577, 1743, 1744, 1735, 1745 Data Sheet

Current clamp set

20 A/200 A 1-, 3-phase

and 3-phase+N

These current clamp sets have been
designed for applications with Fluke
1735 and Fluke 1740 series products for
accurate non intrusive measurement of
ac currents. Using latest technologies
(integrated memory for calibration data)
provides current ranges from 0.5 A up to
200 A in a frequency range of 40 Hz to
5 kHz. The clamps are approved for the
required installation category.

The current clamps are designed for use on insulated conductors. For using it with uninsulated conductors you have to
switch off before attaching the clamp. T he application of the clamps on unin sulated conduc tors is limited to 600 V ac r.m.s.
or dc to ground and frequencies below 1 kHz.
