The Siemens SIRIUS 3RT5075-6AV36 is a size S12 power contactor rated for 400 A in AC-3e duty at 690 V — the rating that governs motor switching in industrial panels. The built-in varistor surge suppressor handles coil suppression without an external module, saving a DIN-rail slot.
Side-by-side mounting is allowed, so multiple S12 contactors can pack into a row without spacing gaps.
It is rated 400 A at 690 V in AC-3e duty, which is the motor-switching rating that determines fit for most induction-motor loads.
