The S0 frame is the compact workhorse in the SIRIUS line, common in control panels for conveyors, pumps, and fans.
For resistive loads (AC-12), it's rated 10 A maximum. The main current circuit uses screw-type terminals accepting 2x (0.25...2.5 mm²) solid or 2x (1...2.5 mm²) stranded, with a max of 2x 10 mm². The auxiliary and control circuit uses spring-loaded terminals — no screwdriver needed for the coil and aux wiring, which speeds up panel wiring. The coil draws 4.2 W DC both on pull-in and hold, so there's no inrush spike to worry about on your 110 V DC supply. Type 2 coordination requires a 35 A gL/gG fuse; Type 1 coordination needs a 100 A gL/gG fuse. That's the selectivity headroom you need to design into your branch circuit protection. The IP20 front keeps fingers out; the IP00 terminal area means it's not touch-safe once wired — standard for panel-mount contactors.
