The LTW300 earth loop impedance testers enable two-wire loop tests with no risk of tripping 30 mA RCDs, even where electronic RCDs are used. The testers are three-phase safe and category IV 300 V rated, making them suitable for use on supplies from 50 VAC single phase to 440 V three-phase installations.
The entry-level LTW315 conducts two-wire non-trip loop testing on supplies between 110 and 280 V, while the LTW325 extends the voltage range to 440 V, as well as adding facilities for displaying max Zs and R1+R2. The LTW335 adds facilities for storing and downloading test results. All units provide PFC calculation as standard.
The testers feature an IP54 weatherproof case, backlit display, folding front cover, standard test leads, mains socket test lead and calibration certificate.
