GF‑718B Medium Blade Fuse Holder Clip | PCB Horizontal Mount, 30A 500VAC, Brass H65 Contacts
The GF‑718B is a horizontal‑mount medium automotive blade fuse clip manufactured by EssFuse. Specifically, it is designed for medium‑size ATO / ATC car plug fuses (GFEFUSE GF‑B series automotive insert fuses). With brass H65 contacts at 0.3mm thickness and tin‑plated terminals, this clip supports rated current up to 30A at 500VAC. Furthermore, it withstands soldering at 260°C for 3 seconds, making it compatible with automated PCB and wiring‑harness assembly. Therefore, this medium blade fuse clip is widely adopted in automotive fuse boxes, BMS distribution boards, and industrial power equipment.
Product Overview
Core Design Purpose
The GF‑718B medium fuse clip targets horizontal mounting in automotive fuse boxes and PCB power distribution boards. Besides, it mates with GFEFUSE GF‑B series medium (ATO / ATC) blade fuses — the most common fuse form factor in passenger vehicles. The horizontal lead layout suits both panel press‑fit and through‑hole PCB soldering.
Electrical Performance
Notably, the GF‑718B carries 30A at 500VAC. Contact resistance stays within 50mΩ maximum. As a result, it maintains stable conductivity under continuous load. Moreover, dielectric strength reaches AC 1000V minimum, confirming reliable isolation between live parts.
Mechanical & Soldering Performance
Insertion and extraction force meets 1kg minimum, ensuring the medium fuse seats firmly without back‑out. In addition, the clip survives soldering at 260°C for 3 seconds, compatible with wave solder and reflow processes. Temperature rise remains below 130°C maximum.

Solutions We Provide
Application Solutions
1. Automotive Fuse Box Integration
For automotive fuse box manufacturers, the GF‑718B offers a horizontal medium‑blade clip that matches standard ATO / ATC fuse layouts. Specifically, the 1kg insertion force balances easy assembly with vibration‑resistant retention. Furthermore, the 260°C / 3s soldering rating supports automated insertion equipment.
2. Battery Distribution Board (BDB) & BMS
In battery management and power distribution boards, the GF‑718B provides a removable medium‑fuse connection for high‑current branches. As a result, service technicians can replace fuses on the bench without desoldering. Therefore, this reduces field repair time and lowers warranty costs.
3. Customization & OEM Support
EssFuse provides custom lead length, contact plating options, and tape‑and‑reel packaging for high‑volume production. In addition, we supply the matching GFEFUSE GF‑B series medium fuses, ensuring mechanical and electrical compatibility. Contact sales for drawings and free samples.

- Marine, caravan and off‑road vehicle electrical system
Customer Questions & Answers
Real Customer Questions
1: What is the difference between GF‑718, GF‑718B and GF‑717C?
A: GF‑718B is the medium (ATO / ATC) blade fuse clip with horizontal leads, brass H65 0.3mm, 30A/500VAC. GF‑718 is an earlier ATO clip rated 40A/250V. GF‑717C is the MINI (smaller) blade version with identical electrical specs. Choose by your fuse body size: GF‑717C = mini, GF‑718B = medium.
2: Is it PCB mount or panel mount?
A: It is a horizontal through‑hole lead clip. The leads can be soldered directly to a PCB, or pressed into a panel / fuse box housing. It is not an SMD part. We provide recommended PCB land pattern on request.
3: Which fuse does it accept?
A: Medium automotive plug fuses (ATO / ATC / regular blade fuses), specifically the GFEFUSE GF‑B series. This is larger than the mini blade fuse used with GF‑717C. Always match the fuse body size to the clip.
4: Can it carry 30A continuously?
A: 30A is the rated value. For enclosed boxes with limited airflow, derate to 70–80% (21–24A). The 130°C max temperature rise already reflects a conservative design margin; pushing full load in sealed cabinets causes overheating.
5: What soldering profile does it survive?
A: 260°C peak for 3 seconds. This covers wave soldering and most reflow profiles. For SMT reflow oven processing, share your exact temperature profile with our engineering team for confirmation.
6: Do you supply the matching medium fuses?
A: Yes. We manufacture the GFEFUSE GF‑B series medium blade fuses that mate with this clip. Sourcing both from EssFuse guarantees insertion force and contact resistance compatibility.
7: Is it RoHS compliant?
A: Yes. Standard tin plating is RoHS compliant. Halogen‑free and special plating options are available on request. RoHS / REACH declarations are provided with formal orders.
