  • TypeElectrical Equipment
  • Dual-element design provides overload and short-circuit protection for service-entrance and switchboard circuits
  • Class RK5 rejection feature prevents incorrect fuse installation in 600 V AC systems
  • 200 kA AC interrupting rating handles high fault currents in transformer and feeder applications
  • 20 kA DC interrupting rating at 300 V DC protects DC circuits up to 70 A

Littelfuse FLSR070 70 A Dual-Element Fuse

The Littelfuse FLSR070 is a dual-element Class RK5 rejection time-delay fuse rated at 70 A. It is designed for service entrance switches, transformers and switchboard main and feeder switches. This fuse suits industrial and commercial electrical installations that require reliable overcurrent protection at 600 V AC and 300 V DC.

High Interrupt Rating for Demanding Circuits

The fuse delivers an interrupt rating of 200 kA and 300 kA at 600 V AC plus 20 kA at 300 V DC. Its Class RK5 rejection feature ensures it fits only compatible fuse blocks, preventing incorrect installation. The time-delay characteristic handles temporary inrush currents without nuisance opening. Buyers needing higher voltage ratings or different interrupt classes should select alternative devices.
