GT-WPR Tubular Wirewound Power Resistors
Green-coated tubular power resistors with metal mounting feet and terminal lugs. The family includes different power configurations and tapped arrangements; select resistance, power and installation dimensions to suit the circuit.
Outline Dimensions
Dimensions in mm. Lettered dimensions correspond to the power-specific outline table. Confirm the mounting arrangement and selected configuration before installation.
Model and Power Comparison
Choose the required model and confirm resistance and operating duty. The photo illustrates family construction; length and terminal arrangement vary with configuration.
Series Outline Dimensions
Dimensions below apply only to the indicated power rows and outline arrangement. Do not interpolate sizes for other power configurations. All dimensions are in mm.
Series Resistance and Mass
Choose a specific resistance within the corresponding range and confirm the required configuration.
Before Ordering
- Match the required model, resistance, power and duty cycle to the circuit.
- Compare the mounting footprint and terminal arrangement with the power-specific drawing.
- Confirm cooling, heat clearance, guarding and insulation requirements for the installation.
- For tapped versions, confirm the number, position and resistance values of the required taps.
Frequently Asked Questions
Why are three resistor forms shown?
The photo shows family construction and a tapped arrangement, not three additional views of one identical unit. Choose the required power and terminal configuration.
Can the same outline dimensions be used for every power?
No. Use the row for the indicated power and outline arrangement; do not interpolate other configurations.
Is resistance fixed by the power rating?
No. Select the required resistance as well as power and duty cycle for the circuit.
What should be confirmed for installation?
Check mounting dimensions, terminals, cooling, heat clearance, guarding and the installation insulation requirements.
