Key Features
- Optimized for 10×38 mm cylindrical fuses, perfectly compatible with GFEFUSE® H10H fuse for renewable‑energy DC‑circuit protection
- Dual‑version options: bolt‑terminal up to 50A; clamp‑terminal up to 30A, rated for 1000VDC new‑energy systems
- High dielectric strength＞1200V; supports 14‑7 AWG wide‑range wire connection with M5 tinned‑copper‑alloy terminals
- Base:PBT; Top‑cover:PC, UL94 V‑0 flame‑retardant, continuous working temperature up to 125 °C for harsh cabinet‑environment
- Galvanized‑steel screw and pressing‑plate, anti‑corrosion and stable clamping performance
- Strict 2.3 N·m installation‑torque specification for preventing over‑heating under full‑load condition
- Compact structure for combiner‑box, inverter cabinet and energy‑storage cabinet internal assembly
Application Overview
H10MF new‑energy fuse holder is engineered for modern renewable‑energy infrastructure. It must be assembled with qualified 10×38 mm DC‑special fuses (GFEFUSE® H10H).
Critical Tip: Distinguish bolt‑version (max 50A) and clamp‑version (max30A). Apply recommended 2.3 N·m torque; select fuse breaking capacity higher than system short‑circuit current.
Installation Steps
- Completely cut‑off DC power before installation and fuse‑replacement work.
- Securely mount H10MF fuse holder inside equipment cabinet.
- Strip cable and connect conductors to M5 terminals, tighten screw to 2.3 N·m (20 in‑LBS) torque.
- Insert matched 10×38 mm qualified DC‑rated fuse (® H10H).
- Close protective top‑cover and double‑check terminal tightness.
- Contact sales for bulk‑order custom‑requirements.
Typical Applications
- Photovoltaic combiner‑box string over‑current & short‑circuit protection
- Battery Energy Storage System (BESS) DC‑side circuit protection
- Renewable‑energy inverter cabinet internal DC‑distribution protection
- New‑energy charging‑pile auxiliary DC‑circuit protection
- General 1000VDC industrial new‑energy power‑distribution assemblies
Pair this H10MF fuse holder with our H10H 10×38 mm fuses for complete renewable‑energy DC‑protection solution.
Safety Reminders
- Disconnect all DC power before servicing. Strictly prohibit live‑line 1000VDC high‑voltage operation.
- Follow 2.3 N·m(20 in‑LBS) torque for M5 terminals; improper torque will generate over‑heat at full‑load.
- Bolt‑type max 50A; clamp‑type max30A. Do not exceed respective current‑rating of each version.
- Only use DC‑specialized 10×38 mm fuses ( H10H). General‑purpose AC fuses cannot be used for 1000VDC PV systems.
- Refer to official datasheet for dimension and full‑spec data before mass‑procurement.
