Size S00 coupling contactor with 24 V DC coil
The 3RT2015-1UB41 is a SIRIUS coupling contactor in the compact Size S00 frame — the smallest footprint in the SIRIUS contactor family, designed for switching auxiliary and control circuits rather than main motor loads.
Panel fit and mounting flexibility
The 45 mm width, 73 mm depth, and 58 mm height fit standard S00 panel layouts. 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.
