Key Features
- 14×51 footprint: Compatible with standard 14×51 cylindrical fuse links up to 50A / 1500V DC
- DIN‑rail mounting: Quick snap‑on installation onto 35 mm DIN‑rail for panel and cabinet assembly
- Bolt terminals: Vibration‑resistant connection, prevents loosening under thermal‑cycling outdoor conditions
- RoHS & REACH compliant: Meets EU environmental requirements for export‑oriented solar and industrial orders
- Serviceable design: Fuse link can be replaced without re‑wiring the fuse base
- Finger‑safe structure: Reduces touch‑risk during high‑voltage DC maintenance work
Application Principle
1500V DC PV and battery storage systems require dedicated DC‑rated fuse protection. The GFEV(H14) fuse base works in conjunction with qualified 14×51 gPV fuse links. It is widely installed inside PV combiner boxes, battery storage cabinets and DC distribution boards for PV‑string overload protection. Important: Select a fuse link whose DC breaking capacity exceeds the system short‑circuit current.
Installation Steps
- Snap the fuse base onto a 35 mm DIN‑rail firmly.
- Connect incoming and outgoing conductors to bolt terminals, apply correct torque per datasheet.
- Insert a properly‑rated 14×51 mm DC‑specialized fuse link.
- Close the protective cover and double‑check terminal torque.
- Custom options such as special pole counts or auxiliary contacts are available upon request when placing orders.
Typical Applications
- PV string and combiner‑box protection for 1500V DC photovoltaic systems
- Battery Energy Storage System (BESS) DC feeder protection
- Industrial DC distribution panels and control cabinets
- EV charging station DC‑side circuit protection
- Solar inverter string‑level protection up to 50A DC
Pair this GFEV(H14) fuse base with our 14×51 mm gPV photovoltaic fuses for a complete high‑voltage DC protection solution.
Safety Notes
- Cut off all DC power before fuse replacement. Never perform live‑line operation on 1500V DC circuits.
- Follow factory‑specified torque for bolt terminals; insufficient torque will cause over‑heating under full‑load current.
- Only use certified 14×51 mm gPV‑grade DC fuses. General‑purpose fuses cannot be used for photovoltaic systems.
- Refer to the official datasheet for exact dimensions and terminal torque before mass‑production procurement.
Häufig gestellte Fragen
Q: Which fuses fit the GFEV(H14) base?
A: This base accepts 14x51mm cylindrical fuse links rated up to 50A at 1500V DC. Always match the fuse voltage rating to your system voltage, please review datasheet before purchase.
Q: What are its electrical ratings?
A: GFEV(H14) is rated 50A, 1500V DC. Do not install fuses higher than 50A. Actual fault‑protection performance depends on the breaking capacity of the selected fuse link.
Q: What compliance standards does GFEV(H14) meet?
A: It complies with RoHS and REACH, suitable for EU‑targeted solar and industrial projects. Compliance documents are available on request.
Q: How is GFEV(H14) mounted?
A: It clips onto standard 35 mm DIN‑rail for fast cabinet installation and remains stable even during repeated fuse changes.
Q: What connection type does it adopt?
A: Bolt‑terminal connection instead of push‑in spring clamps. It offers good anti‑vibration performance and is ideal for outdoor solar installations.
Q: Where is GFEV(H14) commonly used?
A: It is widely used for PV combiners, battery storage cabinets, industrial DC distribution and EV‑charging DC feeders, for any 1500V DC circuit up to 50A requiring field‑replaceable 14×51 mm fusing.
