Fuse, Amp-Trap®, 600VAC, 500VDC, 450A, Time-Delay, Class L, A4BT Series

The high interrupting rating of the Amp-Trap A4BT current-limiting fuses makes it suitable for protecting mains, feeders, and general circuits. The 10-second time-delay at 500 percent of fuse rating is ideal for large motors and other loads with high inrush currents. A4BT fuses can be applied to normal loads up to its full ampere rating to allow 100percent rating of equipment.
