£29.82
The Mersen FR22GR69V135T is a premium Protistor® high-speed cylindrical semiconductor fuse with striker indicator, designed to provide rapid, full-range protection for sensitive power electronic equipment. Manufactured in accordance with IEC 60269-1, IEC 60269-4 and recognised to UL 248-13, this gR characteristic fuse protects semiconductor devices against both overloads and short-circuit faults while minimising let-through energy to maximise equipment reliability. The integrated striker provides immediate mechanical blown-fuse indication and can be used with compatible signalling accessories.
Manufactured in a compact 22 × 58 mm cylindrical format, the FR22GR69V135T is rated at 135 A and 690 V AC (IEC) / 700 V AC (UL). It is ideal for protecting IGBTs, thyristors, SCRs, diodes and rectifiers installed in variable speed drives, UPS systems, industrial inverters, renewable energy equipment and power conversion systems.
With an extremely high interrupting capacity, excellent current-limiting performance and low power dissipation, the FR22GR69V135T delivers dependable semiconductor protection in demanding industrial environments where fast fault clearance is essential.
The Protistor® 22 × 58 mm gR range has been developed specifically for protecting modern semiconductor devices against damaging fault currents. The gR operating characteristic provides comprehensive protection against both overloads and high prospective short-circuit currents, helping reduce thermal stress and extend the service life of expensive electronic components.
The integrated striker indicator enables rapid identification of an operated fuse and supports compatible signalling accessories, reducing maintenance time and improving equipment availability in industrial applications.
