These Edison ECNR30 fuses are a solid choice if you're dealing with motors, transformers, or any AC power distribution setup that needs reliable time-delay protection.
Each fuse is rated at 30 amps and 250 volts, with a true dual-element construction that gives you a minimum 10-second time delay at 5 times the rated current—so it handles startup surges without nuisance blowing.
The Class RK5 rating means it's UL Listed and CSA Certified for safety and performance.
