Product Advantage
The RT18-125 Fuse holder series adopts UL94-V0 flame retardant PA66 housing and integrated thick pure copper conductive frame. This Y-type model retains all mechanical compatibility of standard RT18-125 Fuse holder, while adding visual fault detection function. It meets IEC60269-2 & GB/T 13539.2 standards, and supports max 80kA breaking capacity when matched with gG ceramic fuses, widely used in 800V PV combiner boxes and energy storage AC cabinets.
Dedicated Y Indication Version of RT18-125 Fuse holder Different from standard and W position-signal models, this RT18Y-125 RT18-125 Fuse holder has a built-in transparent window, which aligns with the LED indicator of HM18Y fuse links. Field technicians can quickly identify blown fuses without disassembly, greatly simplifying PV cabinet troubleshooting.
High Safety & Low Temperature Rise Structure Consistent with the reliable conductive design of RT18-125 Fuse holder, thickened pure copper frame ensures stable clamping for long-term full-load operation. Flame retardant PA66 shell resists high cabinet temperature and blocks arc overflow under 800V PV short-circuit faults.

FAQ
Q1: Which fuse link matches RT18Y-125 RT18-125 Fuse holder?
A1: It only supports HM18Y series 22×58mm PV fuse links with LED blown signal, ordinary HM18 fuses cannot display fault status through the window of this RT18-125 Fuse holder.
Q2: Can this Y-type RT18-125 Fuse holder be used in 800V PV combiner cabinets?
A2: Yes, rated up to AC1140V, perfectly adapted to mainstream 800V photovoltaic AC distribution loops.
Q3: Can I replace standard RT18-125 Fuse holder with RT18Y-125 on old PV cabinets?
A3: Yes, unified outline size of the RT18-125 Fuse holder series, direct interchange without changing cabinet mounting holes.
