HRA RESISTOR ASSEMBLIES

Download PDF File

The HRA series of  power, metal clad, wire wound resistors are designed for use in high power inverters.
The basis for these models is an IRV resistors surrounded by a metal case, which conforms to international
safety specifications. The steel case is powder coated and baked for durability.
