(for fuses rated 100e or less)(ansi c37.46). bussmann low amperage, 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.
