Medium Voltage Fuse 1 A 4.8 kV

The Mersen A480T1E is a cylindrical medium-voltage fuse rated at 1 A and 4.8 kV AC. It belongs to the A480T series with a Class E rating and a time-delay characteristic. The fuse has an interrupt rating of 50 kA symmetrical at 4800 V AC. It is designed for non-indicating, non-rejection applications in electrical systems.

Voltage Rating And Series Compatibility

Verify that your circuit operates at or below 4.8 kV AC and requires a Class E-rated, time-delay fuse. The A480T series uses a cylindrical body style with non-rejection mounting. Confirm the available holder accepts a 5-5/8 in length by 13/16 in diameter fuse. Cross-reference the Bussmann AMWNA equivalent series only if your documentation specifies it.

Glass Fiber Reinforced Melamine Body

The fuse body is constructed from glass fiber-reinforced melamine for insulation and mechanical strength. A single-element design provides the time-delay response without an indicator flag. No additional accessories or software are bundled with this fuse. The transparent color allows visual inspection of the element through the tube.

Questions about this item

What comes in the box and do I need any extra hardware to install the Mersen A480T1E fuse?

The fuse is supplied as a single cylindrical unit with glass fibre-reinforced melamine body; no additional hardware is included, so you must provide compatible fuse clips or a holder rated for 4.8 kV AC.

How do I choose the correct version of this fuse for my application?

Select the A480T1E when you need a 1 A, 4.8 kV AC, Class E-rated, time-delay fuse with a 50 kA interrupt rating at 4800 V AC and a 5-5/8 in by 13/16 in cylindrical body.

What does the 50 kA interrupt rating mean once the fuse is fitted in a real circuit?

It means the fuse can safely break a prospective short-circuit current of up to 50 kA at 4800 V AC without rupturing, protecting downstream equipment during a fault.
