Requires 75Vac minimum voltage. Indicating fuses and the LPS-RK-60SP non-indicating fuse are not Vdc rated. Carton quantity Catalog symbols: 10 LPS-RK- SP (non-indicating) Applications LPS-RK- SPI (indicating Feeder and branch circuits Motors Description: Transformers Ultimate protection Class RK1 dual element, Solenoids current-limiting, time-delay fuses available with optional open fuse indication on select ratings. General purpose circuits Time-delay 10 seconds (minimum) at 500% of Features and benefits rated current. Industrys only UL Listed and CSA Certified fuse Rating with a 300kA interrupting rating that allows for Volts simple, worry-free installation in virtually any 600 Vac application. 300 Vdc* Fast short-circuit protection and dual-element, time-delay performance provide ultimate Amps 1/10-60 A protection. IR Reduces existing fuse inventory by up to 33% 300 kA Vac RMS Sym. when upgrading to Low-Peak fuses. 100 kA DC Consistent 2:1 ampacity ratios for all Low-Peak fuses make selective coordination easy. * DC rating does not apply all indicating versions (LPS-RK- Time-delay permits 130% FLA sizing for back-up SPI) and the LPS-RK-60SP, non-indicating fuse. motor protection.
