CB-LPS-RK-100SP   

What's special about these Class RK1 fuses?

  • High degree of current-limitation for maximum short-circuit protection which ultimately means protection of your equipment
  • Provides type 2 protection for IEC and NEMA starters when properly sized so there is no doubt your valuable devices are safe
  • Has two separate elements for overload and short-circuit protection providing time delay for close sizing of high inrush loads which is linked with current-limitation and selective coordination both of which are security against surge damage

These Cooper Bussmann RK fuses are current-limiting, dual-element, time-delay fuses which provide a ten second (minimum) at 500% rated amps (8 seconds for 0-30A sizes) which allows 130% FLA sizing for back-up motor overload protection, and single-phasing protection.

  • End caps are insulated which reduces exposure to energized parts and increases air gap to distance between blades of adjacent mounted fuses or to housing
  • High inrush current motor single-phase protection saves your devices from the harmful surges that can occur
  • Low watt loss power consumption
  • Construction: Copper fuse element
  • Ampere Rating: 70 to 600A
  • One year warranty

The LPS-RK series of fuses are Class R fuses which were created to assist in the prevention of accidental system downgrading. The R Class has a fuse body allowing installation in a fuse clip that will reject both Class H and Class K fuses. This assures that you cannot accidentally downgrade an electrical system designed to be current-limiting.

Class R fuses have an interrupt capacity of 200,000A and are current-limiting, with a rating of either RK-1 or RK-5
