TR150R - 150 Amp Fuse Description
TR150R - 150 Amp Fuse
The TR150R is a 150-amp Class R time-delay fuse used in commercial and industrial electrical systems that require reliable overcurrent protection. It’s designed for you to help protect equipment from short circuits and overloads while allowing normal temporary startup surges to pass without opening the circuit too soon. With a 200 kA interrupting rating at 250VAC, the TR150R is a good fit for applications with higher available fault current. Its current-limiting design helps reduce the fault energy that reaches connected equipment during a short-circuit event. The knife-blade style construction provides a secure fit in compatible fuse holders and distribution equipment. This fuse is commonly used with motors, transformers, HVAC equipment, and power distribution systems where consistent performance and dependable protection are important.
