Fuse Amp-Trap 2000® 600V 1600A Time-Delay Class L A4BQ Series

The Amp-Trap 2000® A4BQ fuse is a Class L time-delay fuse designed for high-performance electrical protection in mains, feeders, large motors, lighting, heating, and general loads. It is suitable for use as circuit breaker back-up and in DC-rated applications such as UPS DC links and battery disconnects. This fuse offers superior current-limiting capabilities, providing enhanced protection for service entrance equipment and downstream circuit components by minimizing short circuit let-thru current.
