Key Features
- Dual‑rating design:32A 690VAC for industrial AC circuits; 32A 1000VDC for PV & energy‑storage DC‑side applications
- Designed for standard 10×38 mm cylindrical fuse links; supports AC general‑purpose fuses and DC‑gPV photovoltaic fuses
- 35 mm DIN‑rail clip‑on mounting for fast assembly inside combiner‑boxes, switch cabinets and control panels
- Robust bolt‑type terminals: anti‑vibration, anti‑loosening under thermal‑cycling for long‑term indoor & outdoor operation
- Finger‑safe housing reduces accidental‑touch risk during high‑voltage DC maintenance work
- Serviceable construction: replace fuse‑link directly without rewiring the whole fuse base
- RoHS & REACH certified, meets EU environmental standards for global export orders
Application Overview
1000V DC solar and energy‑storage systems need dedicated DC‑gPV fuse protection. GF‑FB131 fuse base can match 10×38 mm gPV fuse links for PV‑string protection. For industrial AC projects, use qualified 10×38 mm AC‑rated fuses.
Critical Tip: Always select fuse links whose breaking capacity exceeds the available short‑circuit current of your system. AC‑only fuses cannot be used in 1000V DC photovoltaic circuits.
Installation Steps
- Clip the fuse base firmly onto standard 35 mm DIN‑rail.
- Connect incoming and outgoing conductors to bolt terminals, tighten to torque value specified on official datasheet.
- Insert properly‑rated 10×38 mm fuse link (AC‑type for AC circuit; gPV‑DC‑type for 1000V DC PV circuit).
- Close protective cover and double‑check terminal tightness.
- Custom specifications can be negotiated when placing bulk orders.
Typical Applications
- 1000V DC photovoltaic combiner‑box and PV‑string over‑current & short‑circuit protection
- Battery Energy Storage System(BESS) DC‑feeder protection
- Industrial 690VAC control cabinet and AC distribution‑panel protection
- Mixed AC‑DC power‑distribution cabinets for new‑energy projects
- DC‑side protection for small‑scale EV charging equipment
Pair this GF‑FB131 fuse base with our 10×38 mm AC & gPV photovoltaic fuses for complete AC‑DC multi‑scenario circuit‑protection assembly.
Safety Reminders
- Disconnect all AC and DC power before fuse replacement. Never perform live‑line operation on 1000V DC circuits.
- Follow datasheet‑specified torque for bolt terminals; insufficient torque causes abnormal over‑heating under full‑load current.
- Only use certified gPV‑grade DC fuses for photovoltaic circuits. General‑purpose AC fuses cannot apply for 1000V solar DC systems.
- Refer to official datasheet dimension drawings and electrical parameters before mass‑procurement.
