A4BT2000 - 2000 Amp Fuse

A4BT2000 - 2000 Amp Fuse

The Mersen A4BT2000 Amp-Trap® Class L Time-Delay Fuse is designed for high-amperage electrical systems that need dependable protection against overloads and short circuits. Built for demanding commercial and industrial environments, this 2000A fuse helps you protect mains, feeders, transformers, and large motor applications where temporary startup surges are common. Its time-delay design allows equipment to handle normal inrush currents without unnecessary fuse openings, helping you reduce downtime and keep your operations running smoothly.

With a 200kA interrupting rating, the A4BT2000 delivers strong current-limiting protection that helps minimize damage during fault conditions. It’s rated for both 600VAC and 500VDC systems, making it a versatile option for a wide range of power distribution applications. The fuse features silver-plated copper blade terminals for solid conductivity and a bolted mounting design that provides a secure connection in heavy-duty installations.
