HV Fuses - ABB - Expulsion

High Voltage Fuses from ABB - Connecting World Power Systems

ABB Expulsion Fuse Links are suitable for oil immersed service and use with single and three phase pad-mounted high voltage transformers filled with transformer oil.

ABB Expulsion Fuse Links are designed to protect the high voltage distribution system in the event of an internal transformer fault, secondary fault or severe overload.

ABB Expulsion Fuses are manufactured in Current Sensing, Dual Sensing and Dual Element  types of fuses.

Expulsion fuses are per ANSI C37.40 : "An expulsion fuse is a vented fuse in which the expulsion effect of the gases produced by internal arcing, either alone or aided by other mechanisms results in current interruption." Expulsion fuses will limit the duration of an overcurrent event, but they will not limit the magnitude of fault current. Cooper Bussmann can offer two types of expulsion fuses : replacement fuse links for fused cutouts and boric acid fuses. 

ABB Dual Sensing and Dual Element Fuse Links additionally detect excessive transformer fluid temperature to keep damage caused by extreme temperature environments and long-term overloads from occurring.

ABB DO-III Expulsion Fuse Link is an oil immersed, expulsion type, fuse assembly for use in the ABB DO-III draw out load break expulsion fuse holders or equivalent - designed for use with single and three phase pad-mounted transformers filled with transformer oil or other approved high voltage electrical insulating fluid. ABB DO-III fuse links are designed to protect the distribution system in the event of an internal transformer fault, secondary fault, or severe overload - must be used in series with a current limiting fuse or isolation link.
