® AC: 35-800A 700VAC, 200kA I.R. ® DC: 35-800A 700VDC, 100kA I.R. L/R = 10ms Ratings A70QS Amp-trap® Semiconductor Protection fuses were developed in response to the need for improved overall performance of 700 volt semiconductor fuses for new equipment requirements. A70QS fuses have lower I 2t for better protection, longer life when sub- jected to cyclic loading, plus lower watts loss. A70QS is the best choice to protect dynamic solid state equipment such as motor drives, UPS, etc. ® UL Recognized Component, AC/DC ® AC: Guide No. JFHR2 ® DC: Tested to UL Standard 198L Parameters (35-800A) ® CSA Certified File LR 12636 Approvals HIGHLIGHTS: ® 700V AC/DC Rated ® Very Low l2t ® Low Watts Loss ® Superior Cycling Ability APPLICATIONS: ® Protection of 700V or less motor drives, UPS, inverters, etc. FUSE FUSE BLOCK AMPERE CATALOG RATING NUMBER 35-200 P243C 225-600 P266A 700-800 15C 375 A 70 QS 150 - 4 Amp-trap® Fuse Rated Volts - 700 Style Amperes* Mounting Types* Blades, bolt-in * For ampere ratings and types not listed, consult the factory.
