Description

The Kewtech KEW4140 is a professional solution for electrical installation testing, designed to handle Loop, PFC, PSC, and Phase Rotation measurements with ease. This digital tester features specialized Anti-Trip Technology, allowing for complete trip-free Loop testing on all RCDs rated 30mA and above. This ensures you can perform essential safety tests without unnecessary interruptions to the circuit. Efficiency is built into the design with a dual display that enables simultaneous measurements, such as Loop and PFC/PSC, at the same time. The device is optimized for real-world working conditions, featuring a backlit display and front panel keyboard so you can read results clearly in dark or dimly lit environments. Whether you are conducting high current Loop L-L, L-N, and PSC testing via a two-wire connection or performing polarity checks, the KEW4140 provides the reliable data you need for electrical safety inspections.
