Eaton 4A Time Delay Ceramic Cartridge Fuse 5 x 20 mm 250V AC S505H-4-R

Eaton S505H-4-R ceramic cartridge fuse is a 4A, time-delay fuse designed for use in low-power electronic and electrical circuits operating at up to 250V AC. Its ceramic body construction endures higher thermal and mechanical stress compared to polymer alternatives, making it ideal for demanding industrial and commercial applications.

This fuse's slow-blow characteristic ensures that transient surges typical of equipment start-up do not cause unwanted interruption, while sustained overloads and faults are efficiently cleared to protect sensitive components.

The fuse measures 5 mm in diameter and 20 mm in length, allowing compact installation within miniature PCB fuse holders or control modules. It operates reliably across a wide temperature range from -40°C to +85°C, and is rated for continuous use at up to +125°C in close proximity to heat-generating components.

Highly suitable for safeguarding automation cabinets, power supplies with high inrush currents, and measurement instruments, the S505H-4-R meets international standards including IEC 60127-2, TUV, PSE, cURus, and CCC certifications, reflecting broad global equipment compatibility.

Industrial and commercial users can deploy this fuse within control circuits that require stable protection against overload without nuisance interruptions caused by transient surge currents during startup sequences.

Time-delay protection for low-power electronic circuits and assemblies. Ceramic body for enhanced thermal and mechanical durability. Slow-blow design tolerates current surges during startup. Temperature rating from -40°C up to +85°C with maximum operating temperature of +125°C.

Compact size of 5 x 20 mm fits miniature fuse holders and assemblies. Compliance with IEC 60127-2 and multiple international approvals. Designed for interruption of sustained overloads while passing temporary surges.
