2A 10x38mm 500V Ceramic Cartridge Fuse (50kA)

Industrial-Grade Overcurrent Protection

The 2A 10x38mm 500V Ceramic Cartridge Fuse delivers uncompromising circuit protection for high-density industrial, commercial, and automation infrastructure. Engineered to safeguard sensitive electrical assets against destructive overloads and catastrophic short-circuit conditions, this fuse features a precise 2 Amperes continuous current rating under a maximum operational voltage threshold of 500V AC. Its standardized 10x38mm cylindrical form factor ensures seamless drop-in compatibility with standard modular DIN-rail fuse holders, open-style panel mount blocks, and heavy-duty disconnect switches.

Advanced Mechanical Construction and Thermal Management

Constructed from high-grade, non-combustible alumina ceramic, the fuse body provides superior thermal shock resistance, high structural integrity, and exceptional electrical insulation compared to standard glass alternatives. The interior cavity is packed with high-purity, granular quartz silica sand that acts as an aggressive arc-quenching medium. Upon experiencing a high-fault overcurrent condition, the internal precision-engineered melting element vaporizes, and the surrounding silica sand instantly fuses into a non-conductive glass fulgurite structure, rapidly absorbing thermal energy and extinguishing dangerous electrical arcs before downstream damage can occur.

High Breaking Capacity and Interrupting Dynamics

Featuring a High Breaking Capacity (HRC) rating capable of safely interrupting fault currents up to 50kA at 500V AC, this cartridge fuse reliably isolates severe electrical faults without rupturing or sustaining internal arc flashes. The low I^2t thermal let-through energy characteristic ensures that transient overcurrent surges are cleared quickly, minimizing thermal and electromagnetic stress on connected conductors, programmable logic controllers (PLCs), contactors, and semiconductor devices.

End Cap Engineering and Conductivity

To guarantee minimal contact resistance and long-term corrosion protection in harsh operational environments, the fuse is terminated with dual high-conductivity brass end caps treated with a heavy nickel plating. These heavy-duty caps maintain constant spring-tension contact inside clip-style fuse bases, mitigating resistive heating, voltage drops, and oxidative degradation across extended deployment lifecycles.

Wide-Ranging Application Scenarios

This 2A 10x38mm ceramic fuse is optimized for a vast array of electrical engineering applications, including primary and secondary protection on control transformers, DC-to-AC solar inverter combiner boxes, motor control centers (MCC), auxiliary branch circuit loops, industrial power distribution units (PDUs), and variable frequency drive (VFD) control interfaces. Its ruggedized design renders it ideal for demanding environments prone to high vibration, thermal cycling, and elevated ambient operational temperatures.
