Key Features
- Dual‑rating performance: 63A 690VAC for industrial AC; 50A 1500VDC for PV / energy‑storage DC‑side circuits
- Designed for 14×51 mm cylindrical fuse links, supports both AC general‑purpose fuses and DC‑gPV photovoltaic fuses
- Standard 35 mm DIN‑rail clip‑on design, fast assembly inside combiner boxes and electrical cabinets
- Bolt‑type terminals, stable contact, anti‑vibration and anti‑loosening under thermal cycling for outdoor PV projects
- Finger‑safe housing design to reduce accidental touch risk during high‑voltage DC maintenance
- Serviceable structure: replace fuse link directly without rewiring the whole fuse base
- RoHS & REACH certified, meets EU environmental standards for global solar export orders
Application Overview
1500V DC solar and energy‑storage systems require dedicated DC gPV protection. GF‑FB141 fuse holder matches 14×51 mm gPV fuses perfectly. It is commonly installed in PV combiner boxes, BESS battery cabinets and DC distribution boards for string‑level overload and short‑circuit protection.
Important Tip: Please select gPV fuse links whose DC breaking capacity is higher than the short‑circuit current of your system. AC‑only fuses cannot be used for 1500V DC photovoltaic circuits.
Installation Steps
- Clip the fuse holder firmly onto standard 35mm DIN rail.
- Connect positive and negative conductors to bolt terminals, tighten to the torque value specified on datasheet.
- Insert qualified 14×51mm fuse link (AC‑type for AC circuit; gPV‑DC‑type for 1500V DC PV circuit).
- Close the protective cover and double‑check terminal tightness.
- Custom specifications can be negotiated when placing bulk orders.
Typical Applications
- 1500V DC photovoltaic combiner box, PV string protection
- Battery Energy Storage System (BESS) DC feeder protection
- Industrial 690VAC distribution and control panels
- DC side protection for EV charging stations
- Mixed AC‑DC new‑energy power distribution cabinets
Match this GF‑FB141 fuse base with our 14×51 mm AC & gPV photovoltaic fuses for a complete AC‑DC multi‑scenario DC‑protection assembly.
Safety Reminders
- Disconnect all AC and DC power before fuse replacement. Never perform live‑line operation on 1500V DC circuits.
- Follow factory‑specified torque for bolt terminals; insufficient torque will generate abnormal heat under full‑load current.
- Distinguish AC‑rated fuse and DC‑gPV fuse; ordinary general‑purpose fuses cannot be used for 1500V solar DC circuits.
- Confirm dimension drawing and electrical parameters from official datasheet before mass procurement.
