Resistor Assemblies Assemblies with one or more different types of resistors on frames are available for use as specialty load banks. Resistors with Leads Value-added wiring and connectors allow for a “plug-and-play” solution that easily integrates into the final assembly. Special Resistors Custom resistors are designed-to-order by our engineers and can be customized to fit unique electrical and mechanical constraints. Resistors in Enclosures Available in indoor or outdoor enclosures (IP00, IP20, or IP23), resistors can be pre-wired and assembled for power ratings between 300 W and 100 kW. Pre-Wired Resistor Assemblies Assemblies are wired in parallel or series to meet the needs of the application. Terminal blocks and thermal switches are also available.
