10 x 38 mm Ceramic Cartridge Fuse 12A 380V 100kA

Product Overview

The 10x38mm Ceramic Cartridge Fuse is engineered to deliver high-performance overcurrent and short-circuit protection for demanding industrial electrical systems, power distribution networks, and commercial control panels. Rated for an operating voltage of 380V AC and a nominal current capacity of 12A, this cylindrical fuse link rapidly isolates severe electrical faults to prevent catastrophic component failure, fire hazards, and downstream equipment damage. Designed to operate reliably under harsh thermal and mechanical stress, it serves as a critical frontline defense mechanism in modern power management infrastructures.

Advanced Construction and Material Integrity

Built to withstand extreme thermal shocks and internal pressure surges during fault interruption, the fuse body is manufactured from high-density, non-porous technical ceramic. The interior chamber is tightly packed with high-purity, chemically inert quartz sand that acts as an aggressive arc-extinguishing medium, absorbing kinetic energy and cooling ionized gases instantly when the internal melt element ruptures. The contact caps are precision-stamped from high-grade copper and finished with a durable nickel plating to minimize electrical resistance, prevent oxidation, and ensure low power dissipation during continuous operation.

Technical Specifications and Interrupting Performance

Featuring an exceptional short-circuit breaking capacity rated up to 100kA at 380V AC, this 10x38mm fuse safely quenches massive fault currents without shattering or releasing hazardous plasma. It conforms to standard IEC 60269 industrial protection guidelines, offering fast-acting response characteristics with optimized thermal energy let-through values. The standardized 10mm diameter by 38mm length form factor guarantees seamless integration into standard DIN-rail mounted modular fuse holders, disconnect switches, and inline terminal blocks.

Target Applications and Field Use-Cases

This versatile industrial cartridge fuse is widely deployed across diverse electronic and electrical engineering applications, including:

• Industrial Automation: Protecting PLC digital I/O modules, power supply units, and auxiliary control circuits.
• Motor Branch Circuit Protection: Safeguarding fractional horsepower AC motors and contactors against sustained overloads and phase-to-phase short circuits.
• Commercial HVAC and Power Distribution: Isolating fault conditions in lighting ballasts, fan coil units, and branch circuit panels.
• Renewable Energy Systems: Serving as reliable overcurrent protection in solar PV string combiner boxes, inverter DC inputs, and battery management sub-assemblies.
