The closing power draw hits 920 W DC, then drops to 10 W holding — that inrush spike matters if you're sizing a 24 V DC supply through a converter; the DC holding power is low enough for continuous operation. ## Auxiliary contacts and wiring Built-in auxiliary contacts: 2 NO + 2 NC instantaneous. That's enough for a standard three-wire start/stop circuit with a feedback mirror contact left over. Main terminals are bar-type connections for screw termination, accepting up to 300 mm² at 40 °C or 240 mm² at 60 °C — sized for the 430 A rated operational current at 40 °C ambient. Auxiliary terminals take 2x (0.5-1.5 mm²) or 2x (0.75-2.5 mm²) finely stranded with ferrules. Mounts via screw fixing on a vertical surface, rotatable ±90° or tiltable ±22.5° front-to-back. The S12 frame is a bolt-down contactor — no DIN rail clip on this size. Side-by-side mounting is allowed, but derate for heat buildup when ganged. ## Short-circuit coordination and surge suppression For Type 2 coordination (contactor still usable after fault), 500 A gL/gG. The built-in varistor surge suppressor handles the coil's inductive kick — no external snubber needed unless you're switching the coil with a solid-state output that's sensitive to the 8 kV surge voltage rating.","metaTitle":"Siemens SIRIUS 3RT5075-6AP36-0TH0 Power Contactor, 200 kW at","metaDescription":"Siemens SIRIUS 3RT5075-6AP36-0TH0 power contactor, 200 kW at 400 V AC-3, 220-240 V AC/DC coil, 2 NO + 2 NC aux contacts, S12 frame.

Same coil voltage, same auxiliary contact count, same screw-terminal bar connections. It drops into the same footprint and mounting pattern, so a panel designed for the 3RT5064 can take the 3RT5075 without rewiring, but the reverse would undersize the contactor for a 200 kW motor."},{"question":"What compliance documentation does this brand provide for 3RT5075-6AP36-0TH0?","answer":"The SIRIUS brand provides RoHS compliance with a Substance Prohibitance date of 03/01/2017.
