High Speed
Mersen high speed fuses are specially designed to minimize the I2t, peak current let-through and arc voltage. Ensuring fast opening and clearing of a fault requires rapid element melting. To achieve this, Gould Ferraz Shawmut high-speed fuse element has reduced sections (necks) of a different design than a similarly rated industrial fuse and typically have higher operating temperatures. As a result of their higher element temperatures and smaller packages, high speed fuses typically have higher heat dissipation requirements than other fuse types. To help dissipate heat, the body (or barrel) material used is often a higher grade with a higher degree of thermal conductivity. Bolen's Control House is an authorized distributor of Mersen high speed fuses.
