Thermal Link & Fusing Resistor

Thermal-link & Fusing Resistor (TRXF) is a unique type of Power Resistor, with Over Temperature and Over Current Protections.

The Thermal-link (TCO) is placed through the core of Fusible Wire Wound Resistor (RXF) and in series with RXF. 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.
