Square Body High-Speed Fuse Protistor® Size NH 000 aR 690VAC IEC 315A L Brackets

The 690/700V Protistor® fuse-links provide maximum flexibility in equipment design and ultimate protection for small power conversion equipment. These ultra-fast acting aR fuses have been engineered to provide state-of-the-art protection for semiconductors: diodes, thyristors and IGBT devices. 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. All contact surfaces are silver plated and all hardware is non-magnetic. Each fuse-link can be equipped with a low voltage trip-indicator which can operate a field mountable microswitch.

High-Speed Cylindrical Fuse Protistor® Size 22x58 aR 690VAC IEC 135A With Striker

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.

DIN D Fuse-link gG Size DII 500VAC 500VDC 10A Color code Red

The D fuse-system is the first generation of screw fuse-system in the german DIN standard. It is still used in many installations. Applications are low voltage ditribution units, where non trained persons are allowed to change the fuse-links. The D fuse range comprises the sizes NDZ, DII, DIII, DIV, DV.

DIN D Fuse-link gG Size DII 500VAC 500VDC 16A Color code Grey

The D fuse-system is the first generation of screw fuse-system in the German DIN standard. It is still used in many installations. Applications are low voltage distribution units, where non trained persons are allowed to change the fuse-links. The D fuse range comprises the sizes NDZ, DII, DIII, DIV, DV.

• Reduced size
• Full range protection
• Visual indication of fuse operation
• Safest and most reliable protection system

Cylindrical fuse-link gG Size 14x51 IEC 690VAC 1A

Mersen aM and gG fuse-links cover a wide range of physical sizes and ampere ratings for 400, 500, and 690VAC for protection in electrical distribution circuits and various industrial applications. Most ratings are available in size 8x31 and size 10x38 with an optional indicator, and in size 14x51 and 22x58 with an optional striker to activate an auxiliary contact. Size 10x38 is also available with striker. All cylindrical fuse-links have ceramic bodies and silver-plated contacts. Cylindrical fuse-links "gG" are used for the protection of cables, motors and LV-networks. They limit and cut off unacceptable overcurrents and short-circuit currents up to their nominal breaking capacity. Cylindrical fuse-links "gG" also protect electrical equipment and installations against the dynamic effect of high short-currents. Our technology and process was designed to ensure highly reliable technical performance.

• Multiple body sizes and terminals or blades combination
• aR Class according to IEC 60269-4 and VDE 636-23
• Very low I²t for improved semiconductor protection
• Ultra fast acting
• Current limiting
• Superior cycling capability

Square Body High-Speed Fuse Protistor® Size 70 aR 1250VAC IEC 1300VAC UL 125A Striker Plain Blades

The 1250/1300V Protistor® fuse-links provide maximum flexibility in equipment design and ultimate protection for today's power conversion equipment. These aR ultra-fast acting square body fuse-links are available in different body sizes, each size having multiple worldwide acceptable mounting styles. The Protistor® have been engineered to provide state-of-the-art protection for semiconductors: diodes, thyristors, GTO's and IGBT devices. Fuses are assembled with pure silver, die-cut elements embedded in solidified sand, which helps control arcing characteristics for a lower I²t and high interrupting rating level. All contact surfaces are silver plated and all hardware is non-magnetic. All fuse-links can be equipped with a low voltage trip-indicator which can operate a field mountable microswitch.

• gS Class according to IEC 60269-4
• Low I²t for improved semiconductor protection
• Fast acting
• Highly current limiting
• Excellent cycling capability
• Reduced power dissipation
• No derating in standard NH fusegear
• High widstanding against inrush current and overloads

Fuse Holder UltraSafe™ 800VAC 1000VDC UL Fuse size 22x58 2-Pole Pressure Plate IP20 IP20

The innovative and comprehensive UltraSafe™ range of Mersen fuse-holders. Modular fuse-holders are finger-safe under IEC standards to an IP20 grade of protection, including fuse changing (with the flick of a finger). Modular fuse-holders are available in 1, 2, 3 or 4 poles, with or without visual blown fuse indicator, in UL + IEC version. Multi-pole units can also be field assembled by ordering pin-ties assembly kit. In this size, the range also offers the possibility to use microswitches (supplied with the holders or ordered separately) to allow remote indication. UltraSafe™ range is made of tough and durable thermoplastic or thermoset material.

High-Speed Cylindrical Fuse Protistor® Size 10x38 gR 690VAC IEC 1A

The 10x38 gR cylindrical is a fast acting, full range fuse used in the protection of inverters, UPS, variable speed drives and other discrete semiconductor devices.
