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.
