1 / 7DC Fuse Holder
RT18-32X 4P DIN Rail Fuse Holder 32A 690V
In TN-S and TN-C-S wiring systems, complete circuit isolation requires fusing all three phase conductors and the neutral — leaving the neutral unfused creates a voltage shift hazard under unbalanced loads. The Soltree RT18-32X 4P provides full 3P+N fuse protection in a single four-module housing, making it the correct choice for commercial lighting distribution panels, small HVAC control boards, and any four-wire installation where total disconnection is required by local wiring regulations or system design. Each of the four poles has an independent red LED indicator, so a faulty neutral fuse is just as easy to identify as a phase fault. Rated at 32A and 500V–690V AC, it accepts standard 10x38mm ceramic fuse links and installs tool-free on any 35mm DIN rail. Flame-retardant PVC housing and screw terminals ensure safe, vibration-resistant operation. Note: fuse links are sold separately.
