The In rating is 160 A, with overload protection (Ir) adjustable from 64 A to 160 A, and short-circuit protection (Isd) from 1.2 to 15 times In, plus instantaneous (Ii) from 3 to 15 times In. That adjustability lets you fine-tune the trip to the motor's locked-rotor and starting inrush without nuisance tripping.
Built-in accessories and deployment context
The busbar connection and the accessory set are pre-configured for the 3VA1 platform, so it drops into a panel with the same mounting footprint. For a motor control center or a dedicated pump/conveyor feeder, the undervoltage release provides automatic dropout on supply loss — no separate control relay needed.
