A4BT

Time-delay/Class L

When your heavier loads need protection A4BT fuses won’t

let you down

The high interrupting rating of A4BT current-limiting fuses is ideally suited for

protecting mains, feeders, and general circuits. The 10-second time-delay at 500%

of fuse rating is ideal for large motors and other loads with a high inrush. A4BT fuses

are suitable for DC applications up to 500VDC. An A4BT fuse can be applied to

normal loads up to its full ampere rating to allow 100% rating of equipment, while also

providing superior current-limiting ability.

Features/Benefits:

•

Unique dimensions prevent replacement by other fuse classes.

•

Blade-stamped catalog numbers for permanent identification

•

Glass melamine body and plated terminals provide superior reliability in

harsh environments

Highlights:
