Megger LT300 Earth Loop Tester

This version of the Megger LT300 Earth Loop Tester ships as standard with a set of fused leads and clips. There are also two other models of this tester available that ship with a mains plug and non-fused leads.

Designed to take the difficulty out of carrying out high current loop testing procedures, the Megger LT300 is incredibly simple to use, suitable for use over a wide range of frequencies and uses simple and fast two-wire operation to generate measurements.

When connected to the supply, the Megger LT300 will automatically indicate the supply frequency, setting to the measured supply frequency of 16Hz, 50/60Hz or 400Hz. Once calculated, testing will commence automatically. Two measurement ranges are included: 20Ω with resolution to 0.01Ω and 200Ω with resolution to 0.1Ω.

Suitable for both single and 3-phase testing scenarios, the LT300 will also indicate when an operational supply range of over 330V is detected, ensuring that the accidental phase-to-phase connections on 230V systems do not take place.

The LT300 is ideal for use in a wide variety of different testing scenarios due to its special armoured casing that surrounds the instrument. A built-in cover protects the interface of the tester when not in use, while an IP54 weatherproof rating provides excellent protection in adverse conditions.
