1 / 7DC Fuse Holder
RT18-32X 2P DC Fuse Holder 32A 500V
DC systems differ from AC in one critical way: both the positive and negative conductors carry fault current, which means single-pole fusing leaves a live conductor unprotected during a fault. The Soltree RT18-32X 2P is designed specifically for two-wire DC circuits — protecting both lines simultaneously in a single compact module. It is widely used in photovoltaic string protection, battery bank feeds, DC power supplies, and DC control panels where safe isolation of both conductors is required. Constructed with flame-retardant PVC housing and high-purity copper contacts, it maintains low contact resistance and stable transmission under continuous DC load. Rated at 32A and 500V DC, it accepts standard 10x38mm fuse links. The built-in red LED indicator lights up the moment a fuse blows, pinpointing the fault without tools. A 35mm DIN rail snap-on design and screw terminals allow fast installation in solar inverter cabinets, energy storage enclosures, and DC distribution panels. Note: fuse links are sold separately.
