IEEE/ANSI C37.53.1:1989

Revision Standard - Inactive-Withdrawn.
These tests shall be used to demonstrate that the motor-starter fuses being tested conform with the specified ratings and characteristics. The standard is designed to cover a product that can be used with Class E2 controllers (fused) as described in Table 27.1 and elsewhere in the American National Standard Safety Standard for High Voltage Industrial Control Equipment, ANSI/UL 347-1985.

This standard covers the conformance test procedures for alternating-current high-voltage motor-starter fuses covered in the applicable American National Standards listed in 2.1. High-voltage motor-starter fuses are backup, current limiting fuses used in conjunction with high-voltage Class E2 motor starters.
This standard does not cover installations under the exclusive control of electric utilities for the purposes of communication or metering, or for the generation, control, transformation, transmission, and distribution of electric energy located in buildings used exclusively by utilities for such purposes, or located outdoors on property owned or leased by the utility or on public highways, streets, roads, and the like, or located outdoors by established rights on private property.
