GF‑717B Dual‑Position Mini Blade Fuse Holder Clip | 1‑30A 250VDC, PCB Mount, H65 Brass Tin‑Plated
The GF‑717B is a dual‑position mini automotive blade fuse holder clip manufactured by EssFuse. Specifically, it holds two MINI blade fuses in a single compact PCB‑mount body, rated from 1A to 30A at 12V–250V DC. The housing uses black PBT and PA66 thermoplastic (UL94 V‑0), while PCB terminals are tin‑plated Cu alloy (H65). Furthermore, contact resistance stays below 5mΩ and the operating temperature range covers ‑40°C to 125°C. Therefore, this dual mini fuse clip is widely used in automotive junction boxes, battery management boards, and industrial DC distribution where two circuits need compact side‑by‑side overcurrent protection.
Product Overview
Core Design Purpose
The GF‑717B combines two MINI blade fuse sockets into one through‑hole PCB component. Besides, this dual‑channel design saves board space compared with installing two separate single fuse clips. It targets automotive electronic control units, BMS distribution boards, and DC power supplies needing two protected branches in a narrow footprint.
Electrical Performance
Notably, the GF‑717B supports 12V to 250V DC and 1A to 30A per position. Contact resistance is limited to ≤5mΩ maximum — far lower than comparable single clips. As a result, it minimizes power loss and heat generation even at 30A. Insulation resistance exceeds 10,000 MΩ at 500V DC.
Mechanical & Environmental Performance
The black PBT + PA66 body meets UL94 V‑0 flammability. Moreover, the operating temperature range of ‑40°C to 125°C covers both cold‑climate and under‑hood automotive environments. The tin‑plated H65 copper alloy terminals resist oxidation and maintain stable contact.

Solutions We Provide
Application Solutions
1. Dual‑Circuit Automotive Junction Board
For automotive junction box and body control module makers, the GF‑717B packs two protected branches into one 14.8mm‑long body. Specifically, this halves the board area versus two single clips. Furthermore, the ‑40°C to 125°C range covers both engine bay and cabin electronics.
2. BMS & DC Distribution Dual‑Branch Protection
In battery management and DC distribution boards, the GF‑717B protects two adjacent rails (e.g. main contactor drive + auxiliary sensing). As a result, the ≤5mΩ contact resistance keeps both branches cool even at 30A. Therefore, heat‑related board failures are minimized.
3. Customization & OEM Support
EssFuse provides custom lead length, single‑channel variants, and tape‑and‑reel packaging for high‑volume SMT lines. In addition, we supply the matching MINI blade fuses. Contact sales for the PCB land pattern and free samples.

Customer Questions & Answers
Real Customer Questions
1: What is the difference between GF‑717B and GF‑717C?
A: GF‑717B is a dual‑position (2 fuses) clip with PBT+PA66 UL94V0 body, ≤5mΩ contact resistance, and ‑40 to 125°C range. GF‑717C is a single‑position clip with brass H65 0.3mm, 30A/500VAC, 50mΩ contact resistance, 130°C temp rise. Choose GF‑717B when you need two fuses in one compact body and lower contact resistance.
2: Can I use two different fuse ratings in the two positions?
A: Yes. Each position is independent. You may install different amp ratings (e.g. 10A in channel 1, 20A in channel 2) as long as each does not exceed 30A and the upstream wiring can carry the load.
3: Is it suitable for 12V and 24V automotive systems?
A: Yes. The 12V–250V DC range comfortably covers 12V, 24V and 48V systems. For higher voltage DC (e.g. 400V EV battery packs), consult our engineering team — this holder is designed for low‑voltage control circuits, not high‑voltage traction.
4: What is the operating temperature range?
A: ‑40°C to 125°C. This wide range suits under‑hood automotive environments and cold‑climate outdoor installations. Derate current above 85°C ambient to control temperature rise.
5: Is it through‑hole or SMD?
A: Through‑hole PCB mount. The four pins solder into plated through‑holes. We provide the recommended PCB land pattern drawing on request.
6: Do you supply matching MINI fuses?
A: Yes. We manufacture GFEFUSE GF‑C series MINI blade fuses that fit both positions. Sourcing from one supplier guarantees insertion force and contact compatibility.
7: Is it RoHS / UL94 compliant?
A: The plastic body is UL94 V‑0 rated (PBT + PA66). RoHS compliant. REACH and full documentation are available on formal request.
