IEC Cylindrical Body

Mersen’s Standard Cylindrical fuses provide an extremely high interrupting ratings offering power semiconductor applications the ultimate in electrical protection.
The Protistor® IEC semiconductor fuses offer is comprised of a gR range. The 10x38 gR cylindrical range is a fast acting, full range fuse used to protect from high short-circuit currents and small overload currents.

Mersen’s Standard Cylindrical fuses provide an extremely high interrupting ratings offering power semiconductor applications the ultimate in electrical protection.
The Protistor® IEC semiconductor fuses offer is comprised of an aR range. The 10x38 aR cylindrical range is a high performance, ultra-fast acting fuse for superior short-circuit protection only.

These Protistor® size 22x58 have been designed to protect power semi conductors, complying with standard IEC 60269-4. They are extremely high interrupting rating fuses with large band of ratings (current rating 25 to 135A).
Two models are existing: with or without striker.

These Protistor® size 22x58 have been designed to protect power semiconductors, complying with standard IEC 60269-1 and -4.
They are extremely high interrupting rating fuses: 690 VAC, with large band of ratings (current rating 15 to 135 A).
Two models are existing: with or without trip-indicator

These Protistor® size 14x51 have been designed to protect power semi conductors, complying with standard IEC 60269-1 and -4. They are extremely high interrupting rating fuses: 690VAC, with large band of ratings (current rating 1 to 63A).
Two models are existing: with or without trip-indicator.

The 800VAC Protistor® BS88-4 fuse-link provides maximum flexibility in equipment design and ultimate protection for small power conversion equipment. These fast acting gR fuses have been engineered to provide full range protection to eliminate all overloads and semiconductor fault. They are assembled with die-cut elements embedded in solidified sand, which helps control arcing characteristics for a lower I²t and high interrupting rating level. Each fuse-link is embedded with a trip-indicator.
