Application data

Chance Type MS fuse links have very slow time-current characteristics. In applications where ANSI/NEMA Type T fuse link characteristics are too-fast, the slower characteristics of Type MS can often be utilized.

Fuse-section operation

The fuse element of Chance Type MS fuse links is composed of two copper or copper-alloy wires joined by a solder junction. During heavy overloads or low fault currents, the heat generated by the two wires melts the solder, causing fuse operation. Operation under medium or heavy fault current occurs as one of the two wires melt.

Buttonheads and lengths

The Type MS link is available with only a removable buttonhead.

‡Note: Catalog Numbers shown are 23" overall length; also available in 26" length. †For 26", drop the last two digits.
