For AC-4 switching (plugging, inching, reversing under load), the rated operational current is 6.5 A at 400 V. That's the number that governs contact life in high-duty-cycle reversing applications — not the AC-2 power figure. The main circuit uses spring-loaded terminals, accepting 2x (0.25 to 2.5 mm²) solid or stranded, or 2x (24 to 14 AWG). No screw torque to verify on installation — just strip to 8-10 mm and push in. One normally open instantaneous auxiliary contact is built in, rated 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V. That single aux is enough for a feedback signal to a PLC input or a seal-in circuit, but if you need more than one aux contact, you'll add a side-mount block. ## Coordination and protection — what the fusing specs tell you That's the spec your panel designer needs to match the upstream protection to the contactor's withstand. No conformal coating required inside a standard IP20 panel enclosure. ## Environmental limits and mounting Install inside a panel with at least IP54 enclosure rating if washdown or condensation is a concern. Contact life under full motor current will be lower and depends on the duty category. The 45 mm width and DIN-rail mounting match the standard panel layout for this class.","metaTitle":"Siemens 3RT1015-2AP61 SIRIUS S00 Power Contactor, 3 kW AC-2","metaDescription":"Siemens 3RT1015-2AP61 SIRIUS power contactor, size S00. 3 kW at 400 V AC-2, 4 kW at 690 V.
