The MTBF of 75 a reflects the mechanical endurance typical of this class — 10 million operating cycles — making it a candidate for a critical spare on a conveyor or pump line where downtime costs more than the part. ## Coil and Auxiliary Ratings Coil pick-up and drop-out times are symmetrical: 115-130 ms on both AC and DC, with an arcing time of 10-15 ms. The auxiliary contact block handles 10 A at 24 V, derating to 0.3 A at 220 V — enough for PLC input sensing or relay interposing on a 24 VDC control bus. The screw-type terminals on the coil accept 2x 0.5-1.5 mm² solid or 2x 0.75-2.5 mm² stranded, with a maximum of 2x 0.75-4 mm². Mounting is by screw fixing on a vertical surface, rotatable ±90° and tiltable ±22.5° forward/back. The main power terminals accept stranded conductors from 25 to 120 mm² — sized for the S6 frame's current rating.","metaTitle":"Siemens 3RT1456-6SP36 SIRIUS Contactor, Size S6, 200-277V Co","metaDescription":"Siemens 3RT1456-6SP36 SIRIUS contactor, Size S6 frame, 200-277V AC/DC coil, MTBF 75 a.
