This means the coil pulls in reliably even if the control transformer sags to about 19 V at 50 Hz or 20 V at 60 Hz. For motor switching, the contactor is rated at 4 kW at 400 V in AC-2 duty (slip-ring motor starting) and 8.5 A at 400 V in AC-4 duty (plugging/inching). The AC-4 current is the limiting factor for frequent reversing or jogging applications—if your cycle count is high, that 8.5 A figure, not the motor FLA, governs contact life. Main circuit terminals are screw-type, accepting 2x (0.5...1.5 mm²), 2x (0.75...2.5 mm²), or max 2x (0.75...4 mm²) solid or stranded conductors. In AWG terms, that's 2x (20...16), 2x (18...14), or 1x 12. The IP20 rating on both the front and the terminals means the contactor is touch-safe once installed in an enclosure—no finger access to live parts. Side-by-side mounting is permitted, but a 6 mm clearance to the side is required for heat dissipation when the contactor is continuously loaded. At 24 VAC, the auxiliary contact ratings are 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V—these are the maximums for control-circuit switching, not the main contact current. ## Environmental and coordination The mechanical life is 30 million cycles typical, which is the figure for the contactor assembly itself—auxiliary contact life will be lower depending on load.","metaTitle":"Siemens SIRIUS 3RT1016-1AD05 Power Contactor, S00 Frame, 24","metaDescription":"Siemens SIRIUS 3RT1016-1AD05 power contactor, size S00, 3-pole, 24 VAC 50/60 Hz coil.

The key difference is the coil voltage—the 1AD05 uses 24 VAC, while the 2AP02 uses a different coil voltage. They share the same 45 mm width, screw terminals, and AC-4 current rating, so a panel designed for one can accept the other with a coil voltage change."},{"question":"What are the main contact ratings for motor switching?","answer":"At 400 V, the contactor is rated at 4 kW in AC-2 duty and 8.5 A in AC-4 duty.
