Key Features
- Dual‑rating performance: 125A 690VAC for industrial AC; 80A 1500VDC for PV / energy‑storage DC‑side circuits
- Designed for 22×58 mm cylindrical fuse links, supports both AC general‑purpose fuses and DC‑gPV photovoltaic fuses
- Standard 35 mm DIN‑rail clip‑on mounting, quick 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 construction to minimize accidental‑touch risk during maintenance work
- Serviceable design: replace fuse‑link directly without rewiring the whole fuse base
- RoHS & REACH certified, meets EU environmental requirements for global export orders
Application Principle
GF‑FB221 is a versatile fuse‑base covering both AC and high‑voltage DC scenarios. For AC industrial applications, match with 22×58 mm AC‑rated fuses up to 125A 690VAC. For 1500V DC photovoltaic and battery‑storage projects, install qualified 22×58 mm gPV DC‑special fuses within 80A rating range.
Critical note: Always select fuse links whose breaking capacity exceeds system short‑circuit current. Do not mix‑use AC‑only fuses in 1500V DC solar circuits.
Installation Steps
- Snap 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 22×58 mm fuse link (AC‑type for AC circuit; gPV‑DC‑type for 1500V DC circuit).
- Close protective cover and double‑check terminal tightness.
- Contact sales team for custom requirements upon bulk‑order placement.
Typical Applications
- 1500V DC PV combiner‑box and high‑current photovoltaic‑string protection
- Battery Energy Storage System (BESS) DC‑feeder over‑current & short‑circuit protection
- Industrial 690VAC control cabinet and AC distribution‑panel protection
- Mixed AC‑DC power‑distribution cabinets for new‑energy projects
- DC‑side protection for EV‑charging‑station equipment
Pair GF‑FB221 fuse base with our 22×58 mm AC & gPV photovoltaic fuses for complete AC‑DC multi‑scenario circuit‑protection solution.
Safety Reminders
- Cut off all power supply (AC or DC) before fuse replacement; strictly prohibit live‑line operation especially under 1500V high‑voltage DC condition.
- Observe datasheet‑specified bolt‑terminal torque; insufficient torque will trigger abnormal over‑heating under full‑load current.
- Distinguish AC‑rated fuse and DC‑gPV fuse; AC‑only fuses cannot be deployed in 1500V DC photovoltaic systems.
- Confirm exact dimension drawings and electrical parameters from official datasheet before mass‑production procurement.
