Document coil supply separately from contact voltage class.
Coil selection changes with control net tolerance, pull-in and hold power, auxiliary feedback and pole configuration. Share these inputs with the guide and SKU you are evaluating.

Coil Voltage DC Contactor Guides FAQ
Selection questions
What is the difference between coil and contact voltage?
Coil voltage governs the control circuit; contact voltage class governs the main power path potential.
Which coil guide should I read first?
Match your control supply: 12V or 24V coil articles for panels; 48V/72V when system voltage defines the application.
When do QZJ or CZQ series fit?
Compare QZJ for extended coil voltage programmes and CZQ for pole or reversing configurations.
