Product Description
The TR20R is a 20 A, Class RK5 time-delay fuse from Mersen’s Tri-Onic® TR-R series, ideal for industrial overcurrent protection. Designed to handle motor inrush and transformer startup surges, the fuse limits fault energy to protect downstream equipment. Its rejection-style ends make it easy to install correctly in compatible fuse blocks.
