TR500R - 500 Amp Fuse Description
TR500R - 500 Amp Fuse
The TR500R is a 500 Amp Class R fuse made for your industrial and commercial electrical systems where reliable protection matters. Its time-delay design helps prevent unnecessary fuse openings caused by temporary startup currents from motors, transformers, and similar equipment. That can help reduce downtime and keep systems running the way they should. Built with a knife-blade-style connection, the TR500R provides current-limiting protection to help reduce damage during short circuits and fault conditions. It also carries a 200 kA interrupting rating at 250 VAC for high fault-current applications.
