A4BT900

A4BT900 is a Mersen Amp-Trap Class L time-delay fuse rated for 900 amperes at 600VAC/500VDC with a 200kA AC and 100kA DC interrupt rating.

This current-limiting fuse features a 10-second time delay at 500% of fuse rating, making it ideal for protecting mains, feeders, circuit breakers, and large motors with high inrush currents. The cylindrical body measures 2.5 inches in diameter by 10.75 inches in length and utilizes blade terminals with bolted-on mounting. The glass melamine body and silver-plated copper contacts provide superior reliability in harsh environments. Unique dimensions prevent replacement by other fuse classes, and blade-stamped catalog numbers ensure permanent identification.
