The 240-277 V AC coil means it's wired into a control transformer secondary, not a 24 V DC bus — check your panel's control voltage before specifying. Screw-type terminals on the main circuit accept 2/0 to 500 kcmil AWG cable, sized for the 300 mm² minimum at 40 °C or 240 mm² at 60 °C. Mounting is screw fixing with a vertical surface; the contactor can be rotated ±90° or tilted ±22.5° front-to-back, which gives some flexibility in tight enclosures. Rated insulation voltage is 1 000 V. Pollution degree 3 covers industrial environments with conductive pollution. Switching frequency varies by duty class: 700 cycles/hour for AC-1 resistive loads, 500 cycles/hour for AC-3 motor starting, and 130 cycles/hour for AC-4 plugging/reversing. The general rating is 2 000 cycles/hour for both AC and DC operation — that's the mechanical limit, not the thermal one. For frequent jogging or inching applications, stay within the AC-4 figure. Auxiliary contact ratings: 6 A at 24 V, 1 A at 110 V, 0.3 A at 220 V, 6 A at 230 V, and 3 A at 400 V. The built-in varistor surge suppressor handles coil suppression — no external diode needed, but verify polarity if you're adding a PLC-driven output module. ## Compliance documentation RoHS compliance date is 03/01/2017. No UL or CSA listing is explicitly stated in the evidence.","metaTitle":"Siemens 3RT5075-6AU36 SIRIUS Power Contactor, 240-277V Coil,","metaDescription":"Siemens 3RT5075-6AU36 SIRIUS power contactor, S12 frame, 240-277V AC coil, 133kW at 690V.
