That is the real-world load capacity for a standard three-phase induction motor. The contactor also carries an AC-2 rating of 15 kW at 400 V for slip-ring motors. These duty-specific ratings matter more than a single 'rated current' number because they reflect the actual switching stress. The coil is wound for 50/60 Hz operation at 220-240 V with an operating range of 0.8 to 1.1 times rated voltage. That means it pulls in reliably even if the line sags to 176 V on a 220 V nominal system. Auxiliary contact ratings are given for both AC and DC loads: 10 A at 24 V DC, 6 A at 230 V AC, and 3 A at 400 V AC. ## Mounting and wiring integration The contactor measures 55 mm wide, 112 mm high, and 115 mm deep. Side-by-side mounting is allowed with no derating for the main circuit, which saves panel width when grouping multiple contactors. The main power circuit uses screw-type terminals accepting solid conductors up to 2x 2.5 mm² or stranded up to 2x 25 mm². Auxiliary terminals take solid up to 2x 2.5 mm² or stranded up to 2x 16 mm². The front of the contactor is IP20, so it is touch-safe once installed in an enclosure. The terminals themselves are IP00, meaning they require the panel's own IP rating for protection against solid objects.","metaTitle":"Siemens SIRIUS 3RT1034-3AP60 Power Contactor, AC-3 18.5 kW a","metaDescription":"Siemens SIRIUS 3RT1034-3AP60 power contactor, active production.
