Ferraz Shawmut TRSR20 is a type of fuse manufactured by Ferraz Shawmut, a company that specializes in electrical protection products. The TRSR20 fuse is designed for use in low-voltage systems and has a current rating of 20 amps. It is a time-delay fuse, meaning that it allows a temporary overcurrent to pass through the circuit for a short period of time before clearing the fault. This feature helps to protect equipment and prevent unnecessary tripping of the circuit breaker. The fuse is available in both standard and Class RK5 versions, which is a high-performance, current-limiting fuse.
