It carries three normally-open main contacts and is rated 12.5 A in AC-4 duty at 400 V — that's the heavy switching category for reversing, inching, or plugging where the contacts make and break full motor current under load. The AC-4 figure, not the thermal current, is the one that governs real service life in demanding applications. At 45 mm wide and 85 mm tall, it fits standard S0 contactor spacing in a panel. Screw-type terminals on the main circuit accept solid or stranded copper: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or up to 2x 4 mm². For the power circuit, the range goes to 2x 10 mm². AWG equivalents are 2x (16 to 12), 2x (14 to 10), or 1x 8. The control circuit terminals handle the same solid range. The contactor itself has no built-in instantaneous overcurrent trip — it relies on the upstream protective device for fault clearing.","metaTitle":"Siemens 3RT1024-1AP00-ZW95 SIRIUS Power Contactor, 3 NO, 12.","metaDescription":"Siemens SIRIUS 3RT1024-1AP00-ZW95 power contactor, size S0, 3 NO main contacts, 12.5 A at AC-4 400 V, 7.5 kW at 690 V.
