# What is E rated fuse?

## What is E rated fuse?

E Rated fuses provide transformer protection and are medium voltage,, current limiting, general purpose power fuses that provide overload, and short circuit, protection. E Rated medium voltage fuses are designed to withstand the large magnetizing inrush, that occurs during transformer start-up.

How do I know what size fuses to use?

Find the size of fuse by multiplying the amps required by the device (2) by 1.5. 2×1.25 = 2.5 then we will round up to the nearest fuse size (in multiples of 5 amps) which would call for a 5 amp fuse. Cross Reference that fuse size to verify that it’s below the Maximum fuse size called out by this chart.

### What are the standard fuse sizes?

Standard sizes for fuses and fixed trip circuit breakers, per 240.6, are 15, 20, 25, 30, 35, 40, 45, 50, 60, 70, 80, 90, 100, 110, 125, 150, 175, 200, 225, 250, 300, 350, 400, 450, 500, 600, 700, 800, 1000, 1200, 1600, 2000, 2500, 3000, 4000 5000, and 6000 amps.

How many amps should a fuse be?

However most manufacturers put a 3 amp fuse in the plug as standard.

#### Can I replace a fuse with a higher amp?

Do not replace a blown fuse with one that has a higher amperage rating. The fuse has a specific amperage rating because it is intended to be the weak link in the circuit to protect the electrical components. A blown fuse indicates excessive current has entered the circuit.

How do I choose an amp fuse?

In order to select the right amperage of the fuse, you first need to know the full-load steady-state current of the circuit at an ambient temperature of 25º C (68º F). Once the current value is determined, then a fuse rating should be selected as to be 135% of this value (taken to the next standard value).

## What is 13 amp fuse used for?

13A Fuse – Washing machine, dishwasher, microwave, kettle, toaster, iron.

What are the different fuse ratings?

The standard voltage ratings used by fuse manufacturers for most small- dimension and midget fuses are 32, 63, 125, 250 and 600.
