Bussmann's UL Class RK1 fuse offering includes the industry's most recognized Low-Peak dual-element, current-limiting, time-delay fuses (LPN-RK and LPS-RK) which are also available with optional indication on select ratings (see product data sheet). Complementing the Low-Peak product offering is Bussmann's Limitron family of fast-acting fuses (KTN-R, KTS-R, KWN-R and KWS-R) fuses.
Current limitation for non-inductive circuits provides Class RK1 current-limiting response to maximum ground fault and short-circuit conditions.Provides 10X better current limitation to help prevent equipment damage caused by short-circuit events.Economical solutions for high-fault circuits.Ideal for critical industrial or commercial applications that have specific current limitation requirements.200kA Interrupting rating complies with NEC Section 110.9 for today's large capacity systems.Can be inserted in non-rejection type fuse holders to physically and electrically replace fast-acting Class H, K1, K5, RK5, and other fast-acting fuses.Fast-acting fuse helps prevent equipment damage caused by short-circuit events. Incorporates Class R rejection feature.
