Why Choose the Mersen T215090 DIIGR50V16 Semiconductor Fuse-link?

The Mersen T215090 (DIIGR50V16) is a premium DII Diazed gR semiconductor fuse-link engineered to provide ultra-fast protection for sensitive power electronic equipment. Manufactured by Mersen, a global leader in electrical protection solutions, this fuse is specifically designed to safeguard semiconductor devices against damaging short-circuit currents while maintaining high system reliability.

Featuring a 16 A current rating, 500 V AC operating voltage and a DII screw fuse format with E27 thread, the T215090 is ideally suited for protecting rectifiers, thyristors, variable speed drives, UPS systems and industrial power conversion equipment. Its gR operating class delivers rapid fault interruption, helping to minimise damage to expensive semiconductor components.

Manufactured with a durable ceramic body and offering a 50 kA breaking capacity, the T215090 provides dependable performance in demanding industrial environments. Designed to recognised DIN and VDE standards, it delivers reliable protection wherever high-speed semiconductor fuses are required.
