Fuse monitor - 100 - 690 V | OF series
The OFM Fuse Monitors prevent unsafe neutral voltages ensuring there is no danger for 2-phase motor loading. There is no need for external supply voltage as they operate with all standard fuses. The EMC tested monitor operates with wide voltage ranges of 380-690 VAC and 100-260 VAC +/- 10%. After the blown fuses have been replaced, the fuse monitor is automatically replaced. It features one alarm contact, one trip contact and two LEDs (green and red). Even with phase unbalance it still provides full operational ability. It has snap-on mounting for OS switch fuses or screw mounting for OESA switch fuses and OFAX fuse bases.
