Bolt‑Down Fuse GFE‑0860 Heavy‑Duty DC32V 300A‑1000A
Bolt‑down fuse GFE‑0860 series delivers reliable circuit protection for DC32V heavy‑load circuits. We build this fuse with high‑temperature bakelite housing and high‑conductivity red‑copper terminals, so it handles constant vibration on moving equipment. It covers 300A, 400A, 500A, 800A and 1000A current grades. Furthermore, buyers widely use this fuse for automotive heavy‑duty vehicles, yacht marine vessels, battery power‑supply and off‑grid energy‑storage systems.
Silk‑screen information：We mark the housing with GFEFUSE plus ampere rating by default. In addition, we support custom brand logo printing for bulk orders, and we never print START marking on this model.

제품 특징
- It supports DC32V heavy‑current work, and it delivers reliable overload and short‑circuit protection from 300A up to 1000A for high‑power DC circuits.
- Bakelite insulating housing brings strong flame retardancy, heat‑resistance and impact‑resistance, so it fits harsh onboard working environments.
- High‑purity red‑copper lugs cut contact resistance down, and they effectively stop abnormal temperature rise under continuous heavy‑current load.
- Its dual‑hole bolt‑down mounting design fights vibration and loosening; therefore, it works perfectly for automotive and yacht marine projects.
- We offer flexible silk‑screen service. Besides the standard GFEFUSE marking, we print private‑brand logos for bulk‑volume orders.
Application Areas
- Main battery circuit protection for heavy‑duty trucks and commercial vehicles
- DC power‑supply circuits on yachts, boats and other marine vessels
- Lithium‑battery power‑supply and off‑grid energy‑storage installations
- Safety protection on the input side of high‑power DC‑AC inverters
Installation Precautions
- This bolt‑down fuse only works at DC 32V. Never use it for AC circuits or DC voltage higher than the rated specification.
- Tighten mounting bolts with proper torque. If you apply too little torque, you create poor contact and overheating risk; if you tighten too hard, you crack the bakelite housing.
- Choose a fuse amperage slightly higher than your equipment’s continuous operating current. This trick prevents unwanted blowing caused by startup inrush current.
- Cut off the full power supply before you replace the fuse. Always install a replacement fuse with the exact same rating; never fit a higher‑ampere substitute.
Customization & Packaging
- Silk‑screen Customization：We print GFEFUSE plus ampere rating as standard. If you need a custom logo, send us a vector artwork file for mass orders.
- Packaging Option：We supply bulk loose packing or color‑box packing to match different customer requirements.
자주 묻는 질문
Q1: What is the voltage rating of GFE‑0860 bolt‑down fuse?
A1: The GFE‑0860 bolt‑down fuse runs at DC32V. It targets automotive, yacht marine and battery power‑supply DC circuits. For this reason, you should not install it in AC or higher‑voltage DC systems.
Q2: Can I print my own brand logo for GFE‑0860 fuse?
A2: Yes. We print GFEFUSE and ampere value by default. Moreover, we support custom logo, part‑number and current marking for bulk orders, and you only need to provide a vector logo file.
Q3: Do all current‑rating versions of GFE‑0860 share the same mounting dimensions?
A3: Yes. All variants (300A‑1000A) keep the same outer outline and mounting hole dimension. Only the internal fuse‑link changes to fit different amperage grades.
Q4: What are the housing and terminal material for this bolt‑down fuse?
A4: The outer insulating housing uses bakelite phenolic resin with flame‑retardant property. Meanwhile, conductive terminals adopt high‑purity red‑copper to keep low resistance and low temperature rise.
Q5: How do I select proper ampere rating for automotive or yacht power‑supply?
A5: Pick a fuse rating slightly higher than your system continuous operating current, and reserve enough margin for startup surge‑current. Otherwise, an oversize fuse loses circuit‑protection function.
Q6: What risk will wrong bolt torque bring for bolt‑down fuse?
A6: Under‑torque creates loose contact and over‑heating hazard. On the other hand, over‑torque cracks the bakelite shell. Always disconnect power when you install or swap this fuse unit.
