Why Choose the Mersen FR22AR69V135T High-Speed Fuse?

The Mersen FR22AR69V135T is a premium 135 A high-speed cylindrical semiconductor fuse from the renowned Protistor® 22 × 58 mm aR range. Designed specifically to protect sensitive power semiconductors, this fuse delivers exceptionally fast short-circuit interruption while complying with IEC 60269-4 and UL requirements. It is ideally suited for modern industrial power electronics where reliable semiconductor protection is essential.

With an aR operating characteristic, the FR22AR69V135T provides partial-range protection against short-circuit faults, helping safeguard expensive IGBTs, SCRs, thyristors, diodes and other semiconductor devices. Its 135 A current rating, 690 V AC IEC voltage rating and extremely high 160 kA breaking capacity make it ideal for demanding industrial environments.

This version incorporates an integrated striker indicator, allowing rapid identification of an operated fuse and compatibility with remote indication accessories where required, reducing maintenance time and improving system availability.

Key Advantages

  • High-speed semiconductor protection for critical power electronics.
  • 135 A rated current.
  • 690 V AC IEC / 700 V AC UL ratings.
  • aR operating class for semiconductor short-circuit protection.
