For resistive loads (AC-12), it carries 10 A continuously. The 50 Hz coil operates at 0.8 to 1.1 times rated voltage, so it pulls in reliably even on a soft supply. Size S0 means a 45 mm wide footprint — three of these fit in a standard 145 mm DIN section. Depth is 90 mm, which clears most shallow enclosures. ## Mounting and wiring notes Screw terminals accept up to 2x 10 mm² solid or stranded, or 2x 2.5 mm² with ferrule. AWG equivalents: 2x 16–12, 2x 14–10, or 1x 8. Side-by-side mounting is allowed — no derating required for adjacent units. Pollution degree 3 means it tolerates conductive dust and humidity typical of industrial control panels.","metaTitle":"Siemens 3RT1024-3AH00 SIRIUS Power Contactor, 3 NO, 7.5 kW","metaDescription":"Siemens SIRIUS 3RT1024-3AH00 power contactor, size S0, 3 NO main contacts, rated 7.5 kW at 500/690 V, AC-4 12.5 A.
