SOUKOU ELB-440V Earth Leakage Breaker Tester | Breaker voltage AC 100–440 V, leakage current 0–100 mA/1 A, 1 ms timing, de-energized and live testing

SOUKOU ELB-440V Earth Leakage Breaker Tester: Also Tests AC 440 V Circuits

Overview

The ELB-440V is a dedicated earth leakage circuit breaker tester from Soukou Electric (SOUKOU). It can output its own breaker voltage of up to AC 440 V for de-energized testing, can also test on live circuits, and can test detectors such as earth leakage alarms. Values are held automatically when the breaker trips, and it can also measure circuit voltage.
