SIRIUS S10 — 24 VDC coil, 10 A pick-up inrush
The 3RT1064-2AD36: The coil termination uses spring-type terminals, which speeds wiring and eliminates screw torque checks.
Switching duty and mechanical life
Rated for 750 operating cycles per hour in AC-1 (resistive) duty, 500 ops/h in AC-3 (motor starting), and 130 ops/h in AC-4 (plugging/reversing). The arcing time runs 10-15 ms, and the total operate time (closing + opening) is 40-80 ms on both AC and DC supplies.
Termination and panel fit — 70-240 mm² power side
Main power terminals accept stranded cable from 70 mm² up to 240 mm² — this is a heavy-duty contactor class. Mounting is by screw fixing through a single 11 mm hole. The envelope is 210 mm high, 145 mm wide, 202 mm deep.
