The NON-70 is a non-time delay fuse, intended for use in high-current applications. It is rated for up to 70 amps, and is available in both fast-acting and slow-blow varieties. The fast-acting NON-70 fuse is designed to open quickly in the event of an overload, while the slow-blow version is designed to tolerate short-duration overloads. Both types feature a ceramic body construction and are available in several different sizes and voltage ratings.
