A catalogue current-class number is not a universal full-load or resistive rating for every pole configuration. Use the manufacturer duty tables and the exact terminal/QCT construction. Select the upstream protective device and overload protection for the application.
Typical applications
- Definite-purpose switching in HVAC, refrigeration and resistive-heating equipment.
- OEM motor, compressor, lighting and equipment-control circuits using the documented load ratings.
