Product Advantage
It perfectly matches full-range 0.5A~125A HM18Y ceramic PV fuse links with 22×58mm dimension. Adopting UL94-V0 flame retardant PA66 housing and one-piece thick pure copper conductive frame, this 800V Fuse holder complies with IEC60269-2 & GB/T 13539.2 standards, supporting max 80kA breaking capacity when matched with gG ceramic fuses. Dual signal design realizes on-site manual inspection + unattended PLC remote monitoring, widely applied in intelligent PV combiner boxes and industrial energy storage AC cabinets.
Exclusive Dual-Signal Integrated 800V Fuse holder Different from single W position-signal or single Y viewing-window base, this all-in-one Ceramic Solar Fuse base carries two independent monitoring modules simultaneously. Technicians quickly judge blown fuses via the window without opening cabinet doors; meanwhile, the internal microswitch uploads circuit state to remote control platform, one base meets manual inspection & unmanned PV station monitoring dual demands.

FAQ
Q1: Which fuse link matches this dual-signal 800V Fuse holder?
A1: Only HM18Y series 22×58mm ceramic PV fuses with built-in LED blown indicator can be matched with this Ceramic Solar Fuse base to realize window visual alarm function.
Q2: Can this dual-function Ceramic Solar Fuse base be applied in intelligent 800V PV combiner boxes?
A2: Yes, this 800V Fuse base integrates both on-site visual blown prompt and remote circuit position signal output, perfectly matched with unattended photovoltaic monitoring systems.
Q3: Will the built-in microswitch lose signal after long-term high-temperature cabinet operation?
A3: The auxiliary microswitch passes high temperature & vibration aging test, the signal transmission of this Ceramic Solar Fuse base remains stable after years of continuous running inside sealed PV cabinets.
Q4: Can this dual-signal base directly replace single W/Y type 800V Fuse holder on existing PV cabinets?
A4: The whole series of Ceramic Solar Fuse base share unified outline size, this 800V Fuse holder can be installed directly without modifying cabinet mounting holes for equipment upgrading.
