GF‑700A MAXI Blade Fuse Holder | Heavy‑Duty Large Blade Fuse Socket, PA9T Base, Brass Tin‑Nickel Plated
The GF‑700A is a MAXI large‑blade fuse holder manufactured by EssFuse. Specifically, it accepts MAXI (large) automotive blade fuses — the largest blade fuse form factor used in heavy‑current automotive and marine DC circuits. The black base is molded from PA9T engineering plastic, while the fuse clip is stamped from 0.4mm brass with tin‑nickel plating. Furthermore, the through‑hole lead design suits panel mounting and bolt‑down busbar connections. Therefore, this MAXI fuse holder is widely adopted in heavy‑duty vehicles, RVs, marine electrical systems, and high‑current battery distribution boxes.
Product Overview
Core Design Purpose
The GF‑700A provides a robust socket for MAXI large blade fuses, which handle the highest current levels among automotive blade fuse families. Besides, the PA9T base offers superior heat resistance and mechanical strength compared to standard nylon, making it suitable for under‑hood and high‑temperature engine bay installations.
Electrical Performance
Notably, the 0.4mm brass clip with tin‑nickel plating provides reliable spring contact for heavy‑current MAXI fuses. As a result, it maintains low contact resistance even at high ampere ratings. The PA9T base withstands elevated temperatures without deforming.
Mechanical & Construction
The overall body measures 33.65mm long by 19.28mm wide by 14.10mm high. Moreover, the mounting hole pattern and lead spacing follow standard MAXI holder footprints. The through‑hole leads allow PCB or panel mounting.

Solutions We Provide
Application Solutions
1. Heavy‑Duty Vehicle & Battery Distribution
For truck, bus, RV and off‑road vehicle manufacturers, the GF‑700A hosts MAXI fuses in battery main distribution boxes. Specifically, the PA9T base survives under‑hood heat and vibration. Furthermore, the heavy brass clip carries the high currents found in main battery feeds.
2. Marine & Off‑Grid DC Power
In marine DC electrical systems and off‑grid solar battery banks, the GF‑700A provides serviceable MAXI fuse protection. As a result, technicians can replace a blown main fuse without cutting cables. Therefore, field maintenance is faster and safer.
3. Customization & OEM Support
EssFuse provides custom lead length, terminal options, and packaging. In addition, we supply matching MAXI blade fuses. Contact sales for drawings, samples, and bulk pricing.

Customer Questions & Answers
Real Customer Questions
1: What is a MAXI blade fuse and how is it different?
A: MAXI (large) blade fuses are the largest of the automotive blade fuse family — larger than ATO/ATC medium fuses. They are used for heavy‑current main battery feeds, typically from 30A up to 100A+. The GF‑700A is sized specifically for MAXI fuses, not mini or ATO fuses.
2: What does PA9T base material mean?
A: PA9T is a high‑performance polyamide (nylon) engineering plastic with excellent heat resistance, low moisture absorption, and high mechanical strength. It outperforms standard PA66 / PBT in under‑hood high‑temperature and vibration environments.
3: Is it panel mount or PCB mount?
A: It has through‑hole leads suitable for both PCB soldering and panel mounting. The mounting hole pattern follows standard MAXI holder footprints. We provide the recommended land pattern on request.
4: What current range does it handle?
A: It accepts MAXI blade fuses across the full MAXI amp range (typically 30A–100A+). The holder itself is designed for heavy‑current use; choose the fuse amp rating according to your wiring and load requirements. Confirm exact rating with our engineering team for your application.
5: Do you supply matching MAXI fuses?
A: Yes. We manufacture MAXI blade fuses that mate with this holder. Ordering both from EssFuse guarantees mechanical compatibility and consistent insertion force.
6: Is it RoHS compliant?
A: Yes. Tin‑nickel plated brass clip and PA9T base are RoHS compliant. REACH documentation is available on formal request.
7: Can you customize the lead length or terminals?
A: Yes. Custom lead length, blade terminals, and packaging are available for high‑volume orders. Send your drawing or requirements to our sales team for review.
