ABB Fuses

ABB Fuse links have proven themselves to be suitable for a number of applications, from over-current and short-circuit protection of lines to short-circuit protection of semiconductor and other equipment as well as protection of DC circuits. For motor protection, we recommend to use aM fuse links. The aM fuse links give economical and reliable protection. ABB fuse links for demanding industrial environments are available to be used in the protection of general as well as motor applications.

Superior current limiting capability

The ABB Fuse links limit the unlimited prospective short circuit current to cut-off current. When the low operating energy and cut-off current given in this brochure are used, cables and equipment can be specified without over-dimensioning. For example in the range of low short circuit, the low peak let-through energy protects the overload relay from burning, while during a short circuit the extremely fast operating fuse link protects the contactor contacts from welding and reduces the short-circuit forces in lines and equipment.

ABB offers a full range of DIN-type HRC-fuse links from 2 to 1250 Amperes, 500 V and 690 V. High performance and reliability. Fuses have very high limiting capability, clearing faults rapidly at different voltage and short circuit levels. There is no emission of gases after a short circuit occurs.

Medium voltage current limiting and expulsion fuses suitable for the protection of distribution transformers, voltage transformers, capacitor banks, motor circuits and installations with other switching apparatus.
