Fuse cartridge LechPol WTAT/L 250 mA 20 mm glass (BEZ2000-025Ce)

LechPol WTAT/L 250 mA 20 mm glass fuse cartridge is a cylindrical, top-mounted protective element designed to interrupt excessive current in electronic and electrical circuits. The transparent glass body allows visual inspection of the fuse element, and the compact 20 mm length makes it suitable for panel-mounted holders and many PCB fuse clips. Rated for 250 mA, this glass fuse cartridge provides basic overcurrent and short-circuit protection for low-current applications in consumer electronics, instrument panels and repair tasks.

Advantages

The glass construction permits quick visual verification of fuse condition and makes fault identification straightforward. Its standardized 20 mm form factor fits common panel and PCB holders, simplifying replacement and maintenance. The 250 mA rating is appropriate for protecting small circuits and components from overloads and short circuits while maintaining minimal insertion size.

Suitable for

• Consumer electronics repair and maintenance
• Control and instrumentation panels with 20 mm fuse holders
• PCB-mounted fuse clips for low-current circuits
• Protecting small power supplies, sensors and signal circuits

Key specifications

• Rated current: 250 mA
• Body material: glass
• Mounting style: cylindrical, top-mounted fuse cartridge
• Body length: 20 mm
• Primary function: overcurrent and short-circuit protection for low-current circuits

How to use

Ensure the circuit is powered down and discharged before replacing the fuse. Remove the fuse cartridge from its holder and inspect the blown element through the glass body. Replace with an identical 20 mm glass fuse rated at 250 mA, confirming correct orientation and secure seating in the holder. After replacement, restore power and verify circuit operation. For PCB-mounted installations, use the appropriate fuse clip or holder designed for 20 mm glass cartridges.

Usage recommendations

Use a fuse cartridge with the same current rating and physical dimensions to maintain proper protection. Avoid substituting with higher rated fuses, and replace only with components intended for the same mounting style. Store spare glass fuses in protective packaging to prevent breakage.
