Current transformer WGBU series

encapsulatedhigh-frequencyIEC

The WGBU Series is a compact earth leakage protection system. It is composed of a toroidal transformer with a built-in earth leakage relay. Multi-range electronic relay The sensitivity can be adjusted to 0.03 ... 3 A Trigger delay of 0.02 ... 1 ws, adjustable Type A relay with high frequency current filtering and high immunity. Monitoring in true root mean square (TRMS). LED indicators: Grid connection LED Pre-alarm and trigger LED: 1 flash every 2 s, leak between 25 and 50 % of the sensitivity selected; 1 flash every 1 s, leak between 50 and 75 % of the sensitivity selected; 1 flash every 0.5 s, leak exceeding 75 % of the sensitivity selected; permanently lit, trigger of the earth leakage protection Applications The WGBU series offers a reliable earth leakage protection, with simpler cabling and savings in the assembly time. In addition, installation is very simple, thanks to its compact dimensions.
