Key Features
✅ Heavy‑Duty Square Structure
Reinforced square housing for high‑current loads; anti‑deformation under extreme pressure, ideal for heavy‑duty battery systems.
✅ High‑Current Compatibility
Fits 200A–500A large battery fuses; oversized copper terminals minimize voltage drop and temperature rise.
✅ Vibration & Shock Resistant
Reinforced internal structure + bolted terminals prevent loosening in engine bays, chassis, and heavy‑duty vehicle environments.
✅ Excellent Heat Dissipation
Open‑frame design + high‑grade copper contacts reduce hot spots; stable performance at high ambient temperatures.
✅ Safe & Durable
Flame‑retardant housing resists arc flash and chemical corrosion; long service life in harsh automotive and outdoor conditions.
✅ Easy Installation & Maintenance
Bolt‑on mounting; simple fuse insertion and bolt tightening for quick replacement without complex disassembly.
Common Applications
- Electric Vehicles (EV/HEV): Main battery feed, high‑power auxiliary circuits, battery pack protection
- Energy Storage (ESS): Battery banks, inverter DC inputs, heavy energy storage system circuits
- Solar PV: Large‑scale solar battery storage and heavy PV combiner boxes
- Heavy‑Duty Vehicles: Trucks, buses, construction machinery, forklifts, cranes
- Marine: Yacht/boat battery systems, winches, heavy DC loads
Installation Instructions
- Mounting: Secure the holder to a flat, rigid surface using M8/M10 bolts (torque: 8–12 Nm).
- Fuse Installation: Place square/MEGA/ANL fuse into the cavity; tighten terminal bolts firmly.
- Wiring: Connect thick‑gauge DC cables (2/0 AWG or larger) to the terminals; ensure clean, tight connections.
- Torque Check: Recheck bolt torque after installation and periodically in high‑vibration environments.
