SIRIUS Size S10 Power Contactor — 3RT1065-2NF36
The coil is rated for 96-127 V AC, with an operate time of 80-100 ms on both AC and DC supplies. Arcing time is specified at 10-15 ms, which influences the minimum clearance to grounded metalwork. Mounting is by screw fixing through a single 11 mm diameter hole, with the contactor body measuring 210 mm high, 145 mm wide, and 202 mm deep. The mounting position allows rotation up to ±90° on a vertical surface and tilting ±22.5° forward or back, giving flexibility in tight enclosures.
Duty Ratings and Mechanical Life
The contactor carries switching frequency limits per duty category: 800 operations per hour maximum for AC-1 (resistive loads), 500 ops/h for AC-3 (squirrel-cage motors — starting and running), 500 ops/h for AC-3e (enhanced AC-3), 250 ops/h for AC-2 (slip-ring motors), and 130 ops/h for AC-4 (plugging and inching). The auxiliary switch is present as a factory-fitted component. Its contact ratings are 10 A at 24 V, 2 A at 48 V, 2 A at 60 V, and 1 A at 110 V — these are the maximum continuous currents the auxiliary contacts can break at those voltage levels.
Environmental and Installation Conditions
The power factor at 50 Hz and 60 Hz is listed at 0.4 — this is the load power factor the contactor is rated to switch, typical for motor circuits. Main power connections accept stranded cable from 70 to 240 mm².
