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.
