BK/S505-2A Description

Short technical summary and product information.

The Eaton BK/S505-2A is a ceramic cartridge fuse designed for overcurrent protection in electronic and electrical circuits. It is rated for 2A at 250VAC and offers a breaking capacity of 1.5kA at rated voltage. Its slow-blow response makes it well-suited for applications where temporary inrush currents occur, such as motors and transformers. The melting I²t is 7.6 A²s, providing predictable energy handling during fault events.

 

The fuse is constructed in a standard 5mm x 20mm ceramic cartridge package. Mounting requires a compatible fuse holder, which provides secure connection and easy replacement. The fuse carries approvals from BSI, CCC, CSA, IMQ, SEMKO, UR, and VDE, indicating its acceptance across multiple global markets.

 

This fuse is intended for use as a protective component in power supplies, industrial controls, and other equipment where slow-blow characteristics are needed to avoid nuisance trips during startup surges. Always verify compatibility with the equipment's voltage, current, and breaking capacity requirements before installation.
