The AC-22A utilization category confirms it can switch mixed loads, not just resistive; this covers contactor-controlled motor circuits and heater banks. Rated insulation voltage (Ui) of 500 V AC gives headroom for 400 V systems. Short-time withstand current (Icw) of 1500 A means it can pass fault current for the short duration needed for an upstream protective device to clear — essential for selective coordination. Making capacity (Icm) of 5 kA as a stand-alone switch-disconnector means it can close onto a fault without welding contacts.
