Thermal-Link & Fusing Resistor (TRXF) is an unique type of Power Resistor, with Over Temp. and Over Current Protections. The Alloy Thermal-Link (ATCO) is built in the core of Fusible Wirewound Resistor (RXF) and in series with RXF.

SETsafe | SETfuse TRXF has the same physical size as ordinary RXF as well as large fault current protection. Besides, TRXF can effectively solve the hidden danger of continuous abnormal heat that ordinary RXF may cause when small fault current happens.
