1 / 7DC Fuse Holder
RT18-32X 3P DIN Rail Fuse Holder 32A 690V
Three-phase motor starters, machinery control panels, and industrial distribution circuits require independent per-phase fuse protection — a blown fuse on one phase without isolation can leave the other two phases energizing a damaged motor. The Soltree RT18-32X 3P addresses this directly: three independent fuse positions in one compact 35mm DIN rail module, each with its own red LED indicator, so maintenance teams can identify exactly which phase has tripped without a multimeter. Rated at 32A and 500V–690V AC, it accepts standard 10x38mm ceramic fuse links suited to smaller three-phase loads, control transformers, and auxiliary circuits in motor control centers. Flame-retardant PVC housing and high-conductivity copper contacts maintain stable performance under continuous load, and the tool-free DIN rail clip allows fast installation in any standard control cabinet. Note: fuse links are sold separately.
