Why Choose the Mersen V221439 Semiconductor Fuse?
The Mersen V221439 is an ultra-fast Protistor® semiconductor fuse designed to provide full-range protection for sensitive power electronic equipment. Identified by the commercial designation FR27GB80V16T, it features a gRB (gR) utilisation category, a rated current of 16 A and a rated voltage of 800 V AC, making it ideal for protecting semiconductor devices against overload and short-circuit currents.
The V221439 incorporates an integrated trip indicator (striker), allowing rapid identification of an operated fuse and enabling remote indication when used with compatible accessories. Its 27 × 60 mm cylindrical format makes it suitable for installation in compatible Mersen fuse holders used throughout industrial power conversion systems.
Designed for demanding industrial applications, the V221439 provides low let-through energy and a high interrupting capacity, helping minimise damage to valuable semiconductor devices such as diodes, thyristors, IGBTs and rectifier assemblies.
