Plug Fuse - Time delay - Products
Time-delay plug fuses are screw-in fuses that tolerate the brief current surge when motors and appliances start up, without nuisance blowing, while still protecting against sustained overloads. American Imaginations stocks time-delay plug fuses in Edison-base and Type-S styles across common amp ratings for older fuse panels.
They are ideal for circuits feeding motors, like fridges and pumps. Every time-delay plug 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 does a time-delay fuse do?
A time-delay (slow-blow) fuse withstands a short surge of current, such as a motor starting, without blowing, but still opens on a sustained overload or short. This prevents nuisance blowing on motor circuits.
When should I use a time-delay plug fuse?
Use them on circuits with motor-driven loads that briefly draw high startup current, like refrigerators, freezers, pumps and air conditioners, where a standard fuse might blow on start-up.
Can I substitute a time-delay fuse for a standard one?
Use the fuse type and amp rating specified for the circuit. A time-delay fuse of the correct rating is appropriate for motor loads; never increase the amp rating beyond what the circuit allows.
