LittelfuseĀ® POWR-SPEEDĀ® PSR033FL1400 High Speed Very Fast Acting Semiconductor Fuse, 1400 A, 690/700 V AC/500 V DC, 150/200 kA Interrupt, Class: Class aR, Square Body
LittelfuseĀ® PSR series high speed square body fuses are specially designed for protection of power semiconductor devices such as diodes, TRIACs, IGBTs, SCRs, MOSFETs and other solid state devices that are typically designed into power conversion and power conditioning equipment. Variable frequency drives, inverters, UPS, rectifiers and soft-starters are examples of typical equipment designed with sensitive power semiconductor devices that cannot withstand any line surge or overcurrent conditions and require high speed protection. LittelfuseĀ® POWR-SPEEDĀ® PSR series products offer optimized circuit protection at the extremely fast speed required to protect modern day power conversion devices. Such products are commonly found in numerous applications including pulp and paper industries, cranes and heavy lifting equipment, processing industries, wastewater treatment plants and various large factories and MRO facilities.
High quality steel material. Zinc plated finish. Size is clearly marked on each piece. Precision BrandĀ® keystock is used to provide driving torque between shafts and pulleys, gears, sprockets, etc. Used for new machinery, general maintenance and shop repairs. It is a necessity in all applications where rotating power devices are used. Most tolerances on dimensions are oversized to assure tight fits in keyways for positive, zero backlash power transmission.
