Cartridge Fuse - Products
Cartridge fuses protect circuits and equipment by breaking the connection when current exceeds a safe level, used in disconnects, panels and appliances. Moonshine Bath stocks cartridge fuses in ferrule and knife-blade styles across common amp ratings for residential and light commercial use.
Always replace a fuse with the same type and amp rating specified for the circuit. Every cartridge fuse ships free across the USA, Canada and Mexico, leaves the warehouse within 24 hours on weekday orders before 2 PM EST, and is backed by our price match plus 10 percent beat guarantee.
Frequently Asked Questions
What is the difference between ferrule and knife-blade cartridge fuses?
Ferrule cartridge fuses have rounded metal end caps and are used for lower amp ratings, typically up to 60 amps. Knife-blade fuses have flat blade contacts and are used for higher amperage above 60 amps.
Can I replace a fuse with a higher amp rating?
No. Always use the exact amp rating specified for the circuit. A higher-rated fuse can let dangerous current flow without blowing, creating a fire and equipment-damage risk.
How do I know which cartridge fuse I need?
Match the replacement to the blown fuse's type, voltage and amp rating, which are printed on the fuse body or listed in the equipment manual. If unsure, consult a licensed electrician.
