The Mersen FR14GR69V2 (Item Number Y1017196) is a Protistor® high-speed cylindrical semiconductor fuse designed to provide reliable full-range protection for sensitive power semiconductor devices. Part of the Mersen Protistor® 14 × 51 mm gR series, this fuse is rated at 2 A and 690 V AC (IEC) / 700 V AC (UL), making it ideal for protecting IGBTs, thyristors, diodes and other semiconductor components in industrial power electronics.
Manufactured in accordance with IEC 60269-1 and IEC 60269-4, the FR14GR69V2 offers excellent current-limiting characteristics with an exceptionally high breaking capacity. Its compact 14 × 51 mm cylindrical design enables straightforward installation into compatible fuse holders used in drives, UPS systems and industrial automation equipment.
Unlike the "T" variants, the FR14GR69V2 is supplied without a striker indicator, making it suitable for applications where remote or local fuse indication is not required.
The FR14GR69V2 is engineered to rapidly interrupt fault currents before they can damage expensive semiconductor devices. Its low let-through energy and high interrupting capacity help improve equipment reliability while reducing maintenance costs and unplanned downtime in industrial installations.
Its compact cylindrical design makes it particularly suitable for protecting small inverters, UPS systems, motor drives and other power electronic equipment where dependable semiconductor protection is essential.
