Fuse KEMOT 20 mm 0.4 A ceramic fuse (model BEZ2000-04CE)

KEMOT 20 mm 0.4 A ceramic fuse (model BEZ2000-04CE) is a cylindrical protective component intended for overcurrent protection in electrical circuits and devices that accept standard 20 mm fuses. The ceramic body provides improved thermal stability and mechanical strength compared with glass fuses, making it suitable where higher temperature tolerance or mechanical resilience is required. The rated current of 0.4 A ensures protection for low-current circuits while the standard cylindrical form factor allows installation in common panel holders and fuse clips.

Advantages

The ceramic construction offers greater resistance to thermal stress and containment of arc energy in fault conditions. The compact 20 mm size fits typical fuse holders and panel cutouts, enabling straightforward replacement during appliance repair or maintenance. A clearly specified 0.4 A rating simplifies selection for circuit protection tasks that require low-current interruption. The standard cylindrical design ensures compatibility with a wide range of electronic equipment and control panels.

Suitable for

• Repair and maintenance of household appliances that use 20 mm fuses
• Protection of control panels and industrial instrumentation with low-current circuits
• Electronic equipment and power supplies requiring a 0.4 A protective element
• Replacement in fuse holders, panels, and safety enclosures designed for 20 mm cylindrical fuses

Key specifications

• Body material: ceramic for improved thermal and mechanical performance
• Rated current: 0.4 A for low-current circuit protection
• Form factor: cylindrical, 20 mm length standard
• Mounting: compatible with panel holders and clip-style fuse holders for 20 mm fuses
• Application type: overcurrent protection in appliances, control panels, and electronic devices

How to use

Verify that the circuit is de-energized and that a 0.4 A ceramic fuse is appropriate for the function and ratings of the circuit per system documentation. Remove the old fuse from its holder or panel clip and inspect the holder for signs of damage or corrosion. Insert the KEMOT 20 mm ceramic fuse into the holder, ensuring firm seating and correct polarity where applicable. After installation, restore power and confirm proper circuit operation. Replace fuses only with identical ratings and characteristics to maintain intended protection.

Usage recommendations

Use this ceramic 20 mm 0.4 A fuse as a direct replacement only when the device documentation specifies a 0.4 A protective element and a ceramic body is suitable. For circuits exposed to frequent overcurrent events, inspect the surrounding holder and wiring for root causes before repeated replacement. Store spare fuses in a dry, dust-free environment to preserve integrity.
