Lower Arc-Flash Spacing Requirements. The boundary space required is lower than similar Class RK5 fuses. Lower coordination ratios than Class RK5 fuses makes selective coordination easier. 300kA Interrupting Rating. The Littlefuse Indicator tm fuse is the first indicating power fuse ever.
Money is wasted each time a circuit opens and halts production.
Thousands of dollars can be lost with every minute spent testing to discover the cause. The Indicator tm gives you built-in blown fuse indication with the power off. Just a simple glance at the Indicator's window tells which circuit is open. The circuit can be tested and any problem corrected without unnecessary delay. No time wasted finding the faulted circuit.
