• Low amp, E-Rated medium voltage fuses are general purpose current limiting fuses
• The E rating defines the melting-time-current characteristic of the fuse and permits electrical interchangeability of fuses with the same E Rating
• For a general purpose fuse to have an E Rating the following condition must be met:
The current responsive element shall melt in 300 seconds at a rms current within the range of 200% to 240% of the continuous current rating of the fuse, fuse refill, or link. (For fuses rated 100E or less)(ANSI C37.46)
• Cooper Bussmann low amp, E-Rated fuses are designed to provide primary protection for potential, small service, and control transformers
• These fuses offer a high level of fault current interruption in a self-contained non-venting package which can be mounted indoors or in an enclosure

Description: Indicating and non-indicating E-Rated medium voltage, current limiting fuse links for potential and small power transformers.

Construction: Plated ferrules.
