Eaton Fast Acting Glass Cartridge Fuse 125mA 250V AC 5 x 20 mm S500-125-R

Eaton S500-125-R glass cartridge fuse is a fast acting electrical protection device rated at 125mA and 250V AC with a standard 5 x 20 mm size and 20 mm overall length. It features a transparent glass body which allows users to visually confirm fuse operation and blowing status, simplifying maintenance.

This fuse is part of Eaton's Bussmann S500 series designed according to IEC international standards for reliable global use. It offers low breaking capacity (LBC) to safely interrupt overcurrents and short circuits protecting sensitive electrical components, wiring, and internal circuits from damage.

The fast acting (F) fuse characteristic means it responds quickly to overload conditions but is designed to tolerate brief surges and inrush currents without nuisance tripping. This makes it suitable for protecting less sensitive electronics and cabling from melting or fire hazards in overload situations.

Measuring 5 mm in diameter and 20 mm in length, this cartridge fuse fits standard 5 x 20 mm fuse holders commonly used in board and panel protection across a variety of commercial, industrial, and automation applications.

It is certified by international standards bodies such as VDE, SEMKO, IMQ, CSA, BSI, and CCC, ensuring trustworthy performance and safety compliance. Eaton, formerly known as Bussmann, has long established this fuse series as a dependable choice for circuit protection worldwide.

This glass Cartridge Fuse enables clear visual inspection of fuse condition. The LBC rating defines its breaking capacity suitable for many industrial control circuits. Fast acting characteristic protects circuits quickly from fault currents.

Standard 5 x 20 mm size ensures compatibility with standard fuse holders. Meets multiple safety and performance international certifications. Provides effective protection for electronic, electrical, automation, and commercial equipment.

Designed for repeated replacement after blowing for maintenance ease. Ideal for industrial, laboratory, commercial electrical panel protection, and HVAC applications.

This fuse is essential for preventing damage from overloads and short circuits, ensuring equipment safety and minimizing downtime. For browsing more electrical protection devices including fuses and circuit breakers, explore the Electronics & Electricals category at EnvMart.
