fuses, High Speed, North American Style, Brand Or Series: Class Rk1, Type: Cartridge, Rejection Cap, Amp Rating: 20 Amp, Voltage Rating: 250 Vac/125 Vdc, Interrupting Rating: 200000 Amp Vac Rms Symmetrical, Dimensions: 9/16 Diameter X 2 Length Inch, Featu
KLNR/KLSR series RK1 fast-acting fuses were the earliest type of current-limiting fuse developed. Their single-element, silver link design enables them to provide fast-acting overload and short-circuit protection. When used to protect inductive loads such as motors, solenoids, and transformers, KLNR/KLSR series fuses must be greatly oversized to prevent opening the fuses on harmless inrush currents. In such applications, KLNR/KLSR series fuses may only provide short-circuit protection. Applications: Resistance heaters; Lighting circuits; Non-inductive loads; Molded case circuit breaker load centers and panelboards have increased interrupting ratings when “series rated” with Littelfuse KLNR/KLSR Class RK1 fast-acting fuses. Refer to panelboard manufacturer’s literature for UL Listed combination of fuses and panelboards. Series ratings up to 200,000 amperes are available.
