Fastens with screw fixing, not DIN-rail snap-on. Mounting position is flexible — vertical surface, rotatable ±90°, tiltable ±22.5° front and back. Dimensions: 145 mm wide, 210 mm high, 202 mm deep. That depth matters when you're laying out a panel — 202 mm means it'll clear a standard 250 mm enclosure depth with room for wiring. Wire range on the main terminals accepts 2/0 to 500 kcmil AWG. ## Switching frequency and coil data Maximum mechanical switching rate: 2 000 cycles per hour for both AC and DC operation. For specific duty classes: AC-1 (resistive) max 750 cycles/h, AC-3 (motor start/run) max 500 cycles/h, AC-4 (plugging/inching) max 130 cycles/h. Coil rated voltage is 240–277 V at 50/60 Hz. Coil pick-up current at 24 V is 6 A, at 110 V is 1 A, at 220 V is 0.3 A, at 230 V is 6 A, at 400 V is 3 A. Those are inrush values — the holding current will be lower. The built-in varistor handles surge suppression across the coil. Pollution degree 3 (industrial environment with conductive pollution). Mechanical endurance typical 10 million operating cycles. RoHS compliance substance prohibition date 03/01/2017 — meets current RoHS requirements.","metaTitle":"Siemens 3RT5066-6AU36 SIRIUS Power Contactor, 113 kW at 230","metaDescription":"Siemens 3RT5066-6AU36 SIRIUS Size S10 power contactor.
