This matters when you're fitting into an existing panel where the rail orientation isn't ideal — you won't need a special bracket. ## Wire termination and auxiliary contact ratings That covers most control wiring you'll see in a panel — 14 AWG through 12 AWG stranded fits without a ferrule if the terminal design allows. These are the breaking capacities you need for sizing the auxiliary circuit — the DC ratings drop fast as voltage rises because DC arcs are harder to extinguish than AC. ## Environmental limits and operating times These times matter when coordinating with upstream protection — the total fault-clearing time includes the arcing window. Operating limits: pick-up voltage is 0.8 x rated (19.2 V for the 24 V coil), and the dropout threshold is 1.1 x rated (26.4 V). If your control supply sags below 19.2 V during a brownout, the contactor drops out — design your control transformer and UPS accordingly. The lifecycle stage is listed as current — meaning Siemens still produces this order code as an active catalog item.","metaTitle":"Siemens 3RT2015-1UB41 SIRIUS Contactor, Size S00, 24 V Coil","metaDescription":"Siemens 3RT2015-1UB41 SIRIUS coupling contactor, size S00, 24 V DC coil, screw terminals, 45 mm wide, current production.
