If your control transformer is feeding a 24 VAC bus, confirm the line drop under inrush — the coil draws 5.5 VA at both frequencies, so a long cable run or undersized transformer can sag below the pick-up threshold on a cold start. Closing time is 40-70 ms on AC, same window on DC if you ever drive the coil from a rectified supply. That puts it in the standard range for SIRIUS S6 contactors — fast enough for most conveyor and pump starts, but not a high-speed application where you need sub-20 ms make time. ## Rated operational currents — what the contactor actually carries These are the IEC AC-1 resistive load figures — for motor duty (AC-3) you need to derate further; the S6 frame typically handles 9-12 A in AC-3 but always verify against the motor FLA. ## Panel fit — dimensions and mounting flexibility The contactor measures 150 mm high, 120 mm wide, 128 mm deep — a standard S6 footprint that drops into existing SIRIUS back panels without re-drilling. Mounting position is flexible: vertical surface with +/-180° rotation, or tilt forward/backward up to 30° if the panel layout demands it. ## Wiring terminals — screw-type, double-wire capacity Both main and auxiliary terminals are screw-type, accepting 1x (1-4 mm²) or 2x (1-4 mm²) solid or stranded copper. For a service call where you're landing two outgoing feeds or a daisy-chain from the upstream breaker, the double-wire rating saves a terminal block. The coil terminals are also screw-type, consistent with the main poles.","metaTitle":"Siemens 3RT1355-6AE36 SIRIUS Contactor, AC Coil 24-60 V, S6","metaDescription":"Siemens 3RT1355-6AE36 SIRIUS contactor, size S6, AC coil 24-60 V 50/60 Hz, screw terminals, 2 NO auxiliary contacts.
