Earth-fault detector X72UB6

Product overview
The COMBI 6 multi-channel earth leakage relay X72UB6 is designed to monitor and protect up to 6 independent electrical systems. The 72x72 instrument concentrates multiple inputs in a compact footprint and streamlines wiring thanks to withdrawable terminal blocks. The front panel provides direct access to programming via four keys and a copy/paste function in the settings menu.
