It's rated AC-3 at 6 A up to 440 V and AC-4 for the same current, meaning it handles both normal motor starting and plugging/inching duty without derating. The coil is 575 V AC, which is common for North American 480/277 V panels where you want the control voltage pulled from the same phase as the motor power.
The single NO auxiliary contact (1 NO) is built in; if you need more feedback for the PLC or a status light, you add a side-mount aux block from the TeSys K range. The 575 V coil means you can pull control power from a 480/277 V system without a transformer, but verify the coil tolerance band — it's a 575 V nominal coil, so it holds in on a 480 V line but drops out cleanly on undervoltage.
