ElementDual
- Extremely current limiting - reduces damage to circuits and equipment under short circuit conditions
- Stops damaging short circuits faster than any mechanical protective device
- Reduced costs - current limiting design often permits use of readily available, less costly equipment
- Low resistance design reduces power consumption and utility bills
- Excellent time delay - true dual element construction, with separate non-fatiguing thermally-reversible spring loaded thermal overload element, withstands repeated surges within rated time delay without opening needlessly
- Eliminates needless downtime caused by power surges or equipment demands
- 200 kA at 600 VAC, 20 kA at 300 VDC interrupting rating

Littelfuse® POWR-GARD® LLSRK100 Current Limiting Time Delay Fuse, 100 A, 600 V AC/300 V DC, 200/20 kA Interrupt, RK1 Class, Cartridge Body
Littelfuse® LLNRK and LLSRK series POWR-PRO® fuses provide superior overload and short circuit protection for service entrance, main, feeder and general purpose branch circuits upto 600 A. LLNRK/LLSRK series fuses can be installed in existing Class H fuse blocks to upgrade systems containing lower interrupting rating Class H one-time or renewable fuses.
QO and QOB one, two and three pole thermal magnetic circuit breakers provide overcurrent protection and switching on ac and dc systems. These circuit breakers have an over center, trip free toggle mechanism with quick make, quick break action and positive handle indication. They also have VisiTrip trip indication, which provides a visual indication that the circuit breaker has tripped and interrupted the circuit. A full line of features and factory installed accessories are also available such as shunt trips, auxiliary switches and alarm switches. This 3 pole QO circuit breaker is rated at 50A at 120/240VAC. This unit provides 10kA breaking capacity and bolt on mounting. QO circuit breakers are UL Listed under UL File E84967 and are CSA Certified under CSA Master Contract 153555.
