Class T Fuses

What is a Class T Fuse?

In electronics and electrical engineering, Class T Fuses are a type of low resistance resistor that acts as a sacrificial device to provide over current protection, of either the load or source circuit. Its essential component is a metal wire or strip that melts when too much current flows through it, interrupting the circuit that it connects. Short circuits, overloading, mismatched loads, or device failure are the prime reasons for excessive current. Fuses can be used as alternatives to circuit breakers. A Class T fuse is a fast acting, current limiting fuse that is rated to interrupt a minimum of 200,000 amps.Class T fuses are offered in 300 volt AC and 600 volt AC versions. Ampere ratings range from1 to 800 amps. They have a small footprint, roughly 1/3 the size of a comparable Class R fuse.
