The AC-3e rating also allows 500 ops/h. ## Auxiliary contacts and coil data The coil's rated control voltage is 380–420 V AC; pickup is at 80% of rated voltage (initial value 0.8). Dropout is at 1.1 times the full-scale value. Auxiliary contact ratings: 10 A at 24 V, 2 A at 48 V, 2 A at 60 V, 1 A at 110 V. Mechanical life of the contactor is typically 10,000,000 operations. Overall dimensions: 210 mm height, 145 mm width, 202 mm depth. Mounting uses a single 11 mm diameter hole.","metaTitle":"Siemens SIRIUS 3RT1066-6AV36 Power Contactor, Size S10, 202","metaDescription":"Siemens SIRIUS 3RT1066-6AV36 power contactor, Size S10, screw fixing.
