General Fuse Holder Questions
Most GFEFUSE fuse holders use PBT or glass-filled PBT housing with UL94-V0 flame retardant rating, and brass or phosphor bronze terminals with tin or tin-nickel plating. Panel mount models may also use Bakelite housing for high temperature resistance.
Our fuse holders comply with RoHS and lead-free standards. Selected models carry UL certification with corresponding file numbers. All products are manufactured according to international circuit protection specifications.
PCB mount fuse holders are soldered directly onto printed circuit boards for automated assembly. Panel mount fuse holders are fixed to chassis or equipment front panels with a threaded nut, for easier field replacement and front-panel access.
Most of our fuse holders support both AC and DC circuits. Voltage and current ratings differ between AC and DC; please refer to datasheet for DC breaking capacity.
PCB Mount Fuse Holder FAQs
Yes, most of our PCB mount fuse holders with PBT housing support lead-free reflow soldering. Always check the datasheet for exact soldering temperature and time limits, typically 260℃ for 3 seconds for through-hole models.
A 5×20mm PCB fuse holder is designed exclusively for standard 5×20mm glass or ceramic tubular fuses. It is not compatible with other fuse sizes such as 6.35×31.75mm or blade fuses.
Standard PCB fuse holders have a maximum contact resistance of 5mΩ to 50mΩ, depending on model and current rating. Lower contact resistance means less heat generation and higher efficiency.
PCB mount fuse holders cover ratings from 0.5A up to 30A, depending on model and structure
Automotive Blade Fuse Holder FAQs
We offer blade fuse holders for mini, ATO/ATC (medium), and maxi automotive blade fuses. We also provide universal 3-in-1 models that support multiple fuse sizes in one socket.
Yes, our automotive blade fuse holders are designed for 12V and 24V DC vehicle electrical systems, with rated voltage up to 500VAC for industrial-grade models.
Our standard blade fuse holders have a minimum insertion and extraction force of 1kg, ensuring secure contact under vehicle vibration while allowing reasonable fuse replacement.
Some models are IP54 / IP67 waterproof with sealed housing. Non-sealed versions are for dry cabin installation only. Please refer to product spec sheet.
High Voltage & Industrial Fuse Holder FAQs
Yes, our 6.35×31.75mm tubular fuse holder series (R3-67A / R3-67B) supports up to 1000V DC at 50A, suitable for PV inverters, energy storage systems and industrial DC power supplies.
Dielectric withstand voltage ranges from 1500VAC to over 3000VAC depending on the model. High-voltage tubular fuse holders typically offer above 3000VAC breakdown strength.
Short-circuit breaking capacity depends on model and matched fuse. Our HV fuse holders are tested for solar and energy storage fault current scenarios.
Our high voltage fuse holders adopt touch-proof design to prevent accidental contact with live conductive parts under normal installation.
