The AC-3 maximum switching rate is 800 operations per hour, which covers most conveyor and pump cycling without derating. The S2 footprint (55 mm wide, 114 mm tall, 130 mm deep) fits alongside other SIRIUS S2 components — overload relays, contactor assemblies — on the same rail. ## Integration — clearances and wiring These are the free-air spacings for arc containment and heat dissipation — respect them in a dense panel to avoid nuisance tripping or flashover. Main contact wiring accepts 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded copper. Coil terminals are screw-type, rated for 24 V 50 Hz, drawing 10 A at that voltage. The coil hold-in is reliable down to about 18 V; dropout below that. Arcing time is 10 to 20 ms, and the make/break time (at AC) is 10 to 18 ms. These are fast enough for most motor control circuits but should be coordinated with upstream short-circuit protection (fuse or MCCB) to ensure selectivity.","metaTitle":"Siemens 3RT2036-1AB00-1AA0 SIRIUS Power Contactor, Size S2,","metaDescription":"Siemens SIRIUS 3RT2036-1AB00-1AA0 power contactor, Size S2.
