Description
Resistors with Mounting Hardware
Many standard hardware options allow resistors to be purchased fully assembled, allowing easy integration into the final assembly.
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.
