The EL9250 potential feed terminal with fuse enables the setup of different potential groups with a fused voltage of 120…230 V AC. The supply voltage is taken up via the front terminal contacts, fused and passed through to the adjacent terminals via the internal power contacts. A Power LED and an Error LED indicate the operating state. The fuse is a 6.3 A fuse, which can be replaced at the front.
