LittelfuseĀ® POWR-GARDĀ® KLSR300 Current Limiting High Speed North American Style Fast Acting Fuse, 300 A, 600 VAC/300 VDC, 200/20 kA Interrupt, RK1 Class, Cartridge Body
Resistance Heaters, Lighting Circuits and Non-Inductive Load Applications
UL 248-12 File No. E81895 | CSA File No. LR29862 | PROP65: This product can expose you to chemicals including nickel, which is known to the State of California to cause cancer

LittelfuseĀ® POWR-GARDĀ® Fast Acting Fuse, Current Limiting High Speed North American Style, Series: KLSR, Non-Indicating, 300 A, 600 VAC/300 VDC, 200/20 kA Interrupt, Class: RK1, 50/60 Hz Frequency, Knife Blade Terminal, Holder Mounting, Cartridge Body, Single Element, Melamine, 2-19/32 in Dia x 11-5/8 in L Body

KLSR series RK1 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, KLSR series fuses must be greatly oversized to prevent opening the fuses on harmless inrush currents. In such applications, KLSR series fuses may only provide short circuit protection.

Features

  • Extremely current limiting - stops damaging short circuit current faster than any mechanical protective device
  • Fast-acting - provides fast-acting protection to equipment such as variable speed drives, rectifiers and other equipment containing surge-sensitive components
  • Reliable interruption of all over currents upto 200000 A
  • Longer equipment life - current limiting design reduces damage to equipment caused by heating and magnetic effects of short circuit currents
  • Often permits use of readily available, less costly equipment
  • 200 kA at 600 VAC, 20 kA at 300 VDC interrupting rating
