The 24 VDC magnet coil draws 5.4 W on closing and holding, so the control transformer or DC supply needs to deliver that continuously. Screw-type terminals on the main circuit accept up to 2x 10 mm² stranded or 1x 8 AWG — enough for the 10 A AC-12 maximum or the 12.5 A AC-4 at 400 V.
The S0 footprint is 45 mm wide, 85 mm tall, 101 mm deep — side-by-side mounting is allowed with a 6 mm gap to the side. IP20 on the front, IP00 at the terminals, so it lives inside a closed panel; not for washdown zones.
With type 2 coordination (no welding after a short circuit), the required upstream fuse is gL/gG 25 A. For type 1 (replace after fault), it's 63 A.
