1 Protistor size 70 gr SEMICONDUCTOR PROTECTION FUSES SQUARE BODY HIGH-SPEED FUSE-LINKS AC PROTECTION FEATURES & BENEFITS Excellent cycling capability Multiple body sizes and terminals or blades combination Extremely fast acting Eliminate all overloads Low I²t for improved semiconductor protection gr Class according to IEC and VDE APPLICATIONS The 690V Protistor fuse-links provide maximum flexibility in equipment design and ultimate protection for today s power conversion equipment. These square body fuse-links are available in different body sizes, each size having multiple worldwide acceptable mounting styles. The Protistor gr have been engineered to provide full range protection to eliminate all overloads and short circuit fault. Each fuse is 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. TECHNICAL DATA OVERVIEW Voltage AC 690 VAC Ampere Range (A) A Speed/Characteristic gr I.R.
