The Mersen / Ferraz Shawmut A3T450 is a 450 A fast-acting UL Class T fuse, rated 300 V AC, 160 V DC.
Class T is the most compact current-limiting UL branch-circuit fuse, used where space is tight and let-through energy must be low. A fast-acting fuse opens quickly on an overload, for resistive and lightly loaded circuits with little switch-on surge.
Interrupting rating: 200 kA AC, 50 kA DC.
Construction: 1.62 in (41.1 mm) x 3.06 in (77.7 mm) diameter x length; knife blade with mounting hole.
It is UL Listed and CSA Certified.
