Usage and maintenance

1. Core functions

Fuse protection: compatible with 5 × 20mm cylindrical fuses, supporting overload and short circuit protection

Status indicator: Neon light visually displays whether the fuse is blown or not

Convenient testing: Supports voltage testing in both closed (energized) and open (unpowered) states, and can measure current

Splicing function: Multiple terminal blocks can be mechanically locked through interlocking links (210-254)

2. Steps for replacing fuses

Rotate the fuse holder to the locked open position (automatically locked when installed vertically)

When opening the lid, one end of the fuse will automatically pop out

Manually remove the blown fuse

Insert a new fuse, close the cover to complete the replacement
