This page simplifies the process of selecting the appropriate fuses for both control and 3-phase transformers. We offer a comprehensive table that serves as a quick reference for fuse selection.

Jul 30, 2025 · The Fusing Transformer Calculator helps determine the correct fuse size for the primary winding of a transformer.

The fusing philosophies described in this document have been used for many years to create fuse selection and coordination tables for Eaton’s Cooper Power series fuses used in pad-mounted …

Sep 6, 2023 · The calculator uses this information to calculate the fusing amps based on the input values. The fusing amps calculated by the calculator can be used to select the appropriate fuse or …

Fuse link ratings recommended in these tables will carry the full load of the transformer continuously and will open in five minutes when the transformer load is approximately three times full load.

To assist in the selection of fuses, the following chart recommends the maximum primary fuse rating, in amperes. The first number shown is the maximum overcurrent protection when the primary current is …

Dual Voltage Primary: Transformer shown has a dual voltage primary and is connected for high voltage. For lower voltage, remove jumper "J" and connect H1 to H3 and H2 to H4.

FUSE-FUSE COORDINATION presents various tables for coordinating one type of fuse link behind another type of fuse link. In order to maintain a properly functioning fuse coordination system, the …

This document provides a comprehensive guide to selecting control power transformers and corresponding fuse charts for industrial applications.

For this reason it is important to use a dual element slow blow type fuse - the same type of fuse you would use with a motor. If using a circuit breaker, select a breaker with a time delay – again the …
