High temperature resistant ceramic fuses are available from major distributors such as Mouser, DigiKey, Grainger, DirectIndustry, and Eaton, offering a wide range of ratings and formats for industrial and electronic applications.

Key Distributors and Options

Mouser Electronics offers a broad selection of ceramic cartridge fuses suitable for high-current and high-temperature applications, with datasheets and inventory available for immediate purchase .

DigiKey provides ceramic fuses for both AC and DC circuits, including fast-acting and slow-blow types. These fuses protect against overcurrent, overload, and short circuits, and are suitable for automotive, electronic, and industrial systems .

Grainger Industrial Supply stocks ceramic fuses known for high interrupting capacity and superior thermal resistance, ideal for environments where elevated temperatures or fault energy levels exceed glass fuse capabilities. They are compact, cylindrical, and reliable for demanding electrical conditions .

DirectIndustry lists industrial-grade ceramic fuses, including high voltage and high breaking capacity types. Many fuses feature porcelain tubes with excellent electrical insulation, mechanical strength, and resistance to thermal shocks, suitable for indoor and outdoor use .

Eaton (Bussmann Series) offers MDH ceramic tube fuses with high breaking capacity and surge withstanding capability. These fuses are RoHS compliant, halogen-free, and designed for transient voltage protection in harsh environments, including street lighting and industrial equipment .

Considerations for Selection

• Rated Current and Voltage: Ensure the fuse matches the circuit requirements to prevent damage.
• Fast-Acting vs. Time-Delay: Fast-acting fuses respond quickly to overcurrent, while time-delay fuses tolerate short surges.
• Compliance and Standards: Look for RoHS, UL, IEC, or ATEx certifications for safety and regulatory compliance.
• Mounting Options: Cartridge fuses can be installed in fuse holders, blocks, or with axial leads for PCB or thru-hole applications.

These distributors provide datasheets, technical support, and real-time inventory, making it easier to select the appropriate high temperature resistant ceramic fuse for industrial, electronic, or electrical projects.
