What the 12A Rating Means
The J7KNA-12-10 24: The 12A rating is the continuous current capacity under typical motor or resistive load conditions. For a contactor of this size, 12A covers small motors (up to about 5.5 kW at 400V three-phase, depending on duty class), lighting banks, and small heater loads. It is the number that decides whether this contactor fits your load circuit — match it to the full-load current of the device it switches.
Integration Note
The J7KNA form factor is compact, leaving room alongside other modular control gear. Coil voltage is 24 VDC — verify your control circuit voltage matches before wiring.
