Megger LT300-HIGH CURRENT LOOP TESTER

The Megger LT300 High Current Loop Tester is ideal for CAT IV 300V applications, providing high current loop testing over a wide range of frequencies and voltages. With a resolution of 0.01Ω on the 20Ω range and 0.1Ω on the 200Ω range, the LT300 delivers results quickly, accurately, and steadily. Installations without RCDs are intended for the LT300 loop impedance tester. An enhanced range of applications, such as single phase CAT IV 300V phase to earth and CAT IV 550V phase to phase, are made possible by the broad frequency and voltage ranges. Testing will start automatically as soon as the Megger LT300 loop tester is connected to the supply, and repeat testing is available with a single button press.
