Megger LTW425 Loop Tester

The Megger LTW425 Loop Tester offers precision and reliability for electrical contractors and engineers. Important for those who need fast, accurate testing in various environments. This advanced loop tester is especially useful in applications where the neutral connection is missing or inaccessible. Such as in light switches or systems with 110V center-tapped supplies. By utilizing two-wire testing, the Megger LTW425 eliminates the risk of incorrect connections and saves time compared to traditional testing methods.

Designed to be category IV 300V rated, the LTW425 is safe for use across a wide range of electrical installations. It is suitable for testing supplies between 50V and 300V AC single-phase and up to 440V on three-phase systems. This ensures versatility for a variety of applications.

The Megger LTW425 uses the latest digital processing techniques, allowing it to perform non-trip testing without DC injection. Ideal for installations with electronic RCDs. By separating the test signal from the supply’s fundamental frequency, the tester averages multiple results over time. Ensuring highly accurate measurements. This advanced technology makes it especially effective in noisy environments or systems that require precise fault current calculations.

The LTW range, which includes models such as the LTW315, LTW325, and LTW335, caters to a broad range of testing needs. However, the LTW425 stands out with its enhanced 0.001 ohm resolution. This makes it perfect for applications requiring more precise Prospective Fault Current (PFC) calculations, such as testing high fault current scenarios up to 40kA.

Each Megger LTW loop tester comes housed in a robust IP54-rated weatherproof case and includes a backlit display for easy readability. The testers also feature a folding front cover for added protection. The test is supplied complete with standard test leads, a mains socket test lead and a calibration certificate, making them ready for immediate use on-site.
