  • TypeFuses & Accessories
  • ColorTransparent
  • Reliable over-current protection with 50 kA interrupt rating at 4.8 kV
  • Consistent time-delay operation prevents nuisance tripping during transient surges
  • Durable glass fibre-reinforced melamine body withstands harsh environments
  • Compact 5-5/8 in cylindrical design fits standard E-rated fuse holders
  • Direct Bussmann AMWNA cross-reference simplifies specification and replacement

Medium Voltage Protection

The Mersen A480T2E is a 2 A, 4.8 kV AC time-delay fuse designed for medium-voltage circuits. It suits engineers and maintenance teams who need reliable overcurrent protection in industrial or utility equipment. The cylindrical, non-indicating body fits standard clips without a rejection feature. Buyers needing a visual trip indicator or a different interrupt class should look elsewhere.

Capacity and Interrupt Rating

Rated at 2 A continuous current, the fuse carries normal loads while the time-delay characteristic tolerates temporary inrush without nuisance opening. It interrupts up to 50 kA symmetrical at 4800 V AC, providing substantial fault-current headroom for medium-voltage switchgear. Circuits exceeding 2 A or requiring a faster-acting curve will exceed its design envelope.

Construction and Mounting

The 13/16 in diameter by 5-5/8 in length glass fibre-reinforced melamine body resists tracking and mechanical stress. A single element inside the transparent tube ensures consistent melting behaviour. Non-rejection mounting means it installs in existing clips but offers no keying against incorrect ratings. Installers must verify clip spacing and voltage clearance themselves.

Questions about this item

Will the 13/16 in diameter cylindrical body fit the fuse clips on my existing 4.8 kV switchgear?

The fuse measures 13/16 in diameter and 5-5/8 in length, matching the A480T series cylindrical dimensions used in standard E-rated medium-voltage clips.

Does the glass fibre-reinforced melamine body come with mounting hardware or must I order clips separately?

The fuse is a single-element cylindrical unit only; compatible clips or fuse holders for the 13/16 in diameter must be sourced separately.
