E-Rated Fuses

2.75kV to 38kV

10 to 450A

Bussmann E-Rated Fuses

Bussmann’s E-Rated Medium Voltage Fuses are defined by their melting time-current characteristic that permits their electrical interchangeability with other fuses of the same E Rating. Bussmann’s E-Rated fuses are available in ferrule, bolt-on and clip-lock and speciality mount fuses for Ampgard start motors.

Typical applications include medium transformer primary protection, medium feeder circuit protection, medium voltage switches, medium metal-enclosed switchgear and direct OE replacements.
