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