Three normally-open main contacts handle the power path; screw-type terminals accept 2x (0.25...2.5 mm²) solid or stranded, with a maximum of 2x 10 mm² per clamp. The AC-4 switching current at 400 V is 12.5 A, which governs the contactor's life under severe inrush or plugging duty — the mechanical endurance is 10 million cycles, but electrical life under AC-4 will be lower. For resistive loads (AC-12), the continuous current is 10 A. The 90 mm depth fits standard 100 mm deep enclosures; the 85 mm height leaves clearance for busbar covers or auxiliary contact blocks.","metaTitle":"Siemens 3RT1024-3AF00 SIRIUS Power Contactor, Size S0, 7.5 k","metaDescription":"Siemens 3RT1024-3AF00 SIRIUS power contactor, Size S0, 3 NO main contacts, 7.5 kW at 500/690 V, screw terminals, 45 mm wide, IP20 front.
