It fastens with a screw or snaps onto standard 35 mm DIN rail per DIN EN 60715, and the mounting position allows +/-180° rotation on a vertical surface plus +/-22.5° tilt forward and backward — handy when you're squeezing it into a tight enclosure corner.
The coil termination uses spring-type terminals, not screw clamps — that saves a few seconds per wire on the assembly bench and holds firm under vibration on a conveyor line. The main contact ratings are given by voltage class: at 24 V DC it switches 10 A, at 48 V DC it handles 2 A, at 60 V DC it's rated 6 A, and at 230 V AC it manages 10 A. For higher voltages, it's rated 3 A at 400 V, 2 A at 500 V, 1 A at 690 V, and 0.1 A at 600 V. These numbers tell you the contactor is sized for moderate motor loads and general-purpose switching, not for high-current heating banks.
