Mechanical life is rated at 10 million operations typical, and the electrical endurance varies by duty cycle: 1000 operations per hour at AC-1 (resistive loads), 800 per hour at AC-3 (motor starting), and 300 per hour at AC-4 (plugging/inching). Main circuit terminals accept solid wire from 2x (0.5 to 1.5 mm²) up to 2x (0.75 to 4 mm²) for the smaller range, and stranded wire from 2x (0.75 to 25 mm²). The combined solid-or-stranded range covers 2x (0.75 to 16 mm²). That's a wide clamp — covers everything from control-circuit tails up to the main motor feed for a 30 kW load. No ferrule required for stranded, but it's good practice on the smaller gauges. Coil operating range is 0.8 to 1.1 times rated voltage at 50 Hz, 0.85 to 1.1 at 60 Hz. Pickup time at AC is 7 to 20 ms, arcing time 10 to 15 ms — fast enough for most sequencing but not a high-speed transfer switch. The auxiliary contact ratings cover 24 V at 10 A, 60 V at 2 A, 110 V at 1 A, 220 V at 0.3 A, 230 V at 6 A, and 400 V at 3 A — enough for pilot-duty control circuits.","metaTitle":"Siemens 3RT1036-1AD20 SIRIUS Power Contactor, 30 kW at 500 V","metaDescription":"Siemens 3RT1036-1AD20 SIRIUS power contactor, size S2, 30 kW at 500 V AC-3.

The 3RT1036-1AD20 has screw-type terminals; if your panel is wired for screw clamps, the 3RT5036-1AB00 would require a terminal adapter or re-termination. The 3RT5036-1AP00 and 3RT5036-1AH00 are other spring-cage variants with different coil voltages. All share the same 55 mm width and DIN rail footprint, so mechanical fit is identical."},{"question":"What is the depth of 3RT1036-1AD20?","answer":"The depth is 115 mm. Combined with the 55 mm width and 112 mm height, it fits a standard S2 contactor footprint on DIN rail."},{"question":"Will 3RT1036-1AD20 drop into a panel specified around 3RT5036-1AB00?","answer":"Yes, the physical footprint is identical — both are S2 frame, 55 mm wide, DIN rail mount per EN 50022. The difference is termination: the 3RT1036-1AD20 uses screw-type terminals, while the 3RT5036-1AB00 uses spring-cage. If the panel was wired for spring-cage, you'd need to swap to screw-clamp wiring or use a terminal adapter.
