The coil is rated for 23 to 26 V, so it operates on a nominal 24 VDC supply with a hold range that covers typical voltage sag. The 3RT1054-1AB36 is a Size S6 contactor, which dictates the physical footprint and the maximum continuous current it can handle. The main power terminals accept stranded conductors from 16 to 70 mm², so it is sized for motor feeders in the range of roughly 30 to 65 A at 400 V, depending on the duty cycle. The auxiliary contact block is present, with ratings that vary by voltage: 10 A at 24 V, 2 A at 48 V or 60 V, 1 A at 110 V, 0.9 A at 125 V, and 0.3 A at 220 V. Switching frequency limits are duty-specific: 1,000 operations per hour in AC-3 (motor starting) and AC-3e, 800 in AC-1 (resistive), 400 in AC-2 (slip-ring motor), and 130 in AC-4 (plugging/inching). If your application requires frequent jogging, the AC-4 limit of 130 cycles/hour is the binding constraint. Mounting is by screw fixing, not snap-on DIN rail. This gives flexibility in panel layout, but the screw fixing means you need to account for drilling and tapping the mounting plate. Dimensions are 172 mm high, 120 mm wide, and 170 mm deep. These are minimum air gaps for heat dissipation and arc containment; do not compress them in a tight panel. This covers most indoor industrial environments without derating.","metaTitle":"Siemens 3RT1054-1AB36 SIRIUS Power Contactor, Size S6, 170mm","metaDescription":"Siemens SIRIUS 3RT1054-1AB36 power contactor, Size S6, screw fixing.
