0.5A 500V 10x38mm Ceramic Cartridge Fuse (50kA Interrupting Capacity)

High-Performance Overcurrent and Short-Circuit Protection

Engineered for high-reliability circuit protection, this 0.5A 10x38mm ceramic cartridge fuse delivers exceptional safeguarding against overcurrent events and short circuits in industrial and commercial electrical systems. The fuse is constructed with a high-grade ceramic cylindrical tube that offers superior dielectric strength and resistance to thermal shock. The internal cavity is packed with high-purity, granular silica sand that acts as an advanced arc-quenching medium, rapidly absorbing thermal energy and suppressing plasma arcs generated during high-energy fault clearances to prevent damage to sensitive hardware.

Robust Industrial Specifications and Material Engineering

Rated for operational voltages up to 500V AC with a high interrupting capacity of 50kA, this cartridge fuse is built to isolate high peak short-circuit currents safely without rupturing. The heavy-duty end caps are crafted from high-conductivity alloy steel plated with nickel, ensuring minimal contact resistance, robust resistance to atmospheric oxidation, and long-term mechanical integrity. The precision-calibrated melt element provides tight current tolerance, minimizing power dissipation and operational heat generation during steady-state conditions.

Versatile Applications and System Integration

Designed to fit standardized 10x38mm (midget) fuse holders, panel-mount blocks, and DIN-rail disconnector switches, this fuse provides versatile protection across diverse electronic and electrical architecture. It is heavily utilized for safeguarding PLC digital and analog I/O modules, power supplies, digital multimeters, control power transformers, auxiliary circuits, power distribution units (PDUs), and solar photovoltaic string monitoring equipment.
