The coil pulls 12.5 VA at 50 Hz, 24 V rated value; the contactor is designed for screw and snap-on mounting onto 35 mm standard mounting rail per DIN EN 50022, which is the common DIN-rail profile in European control panels. Depth is 115 mm, width 73 mm, height 112 mm — check your enclosure depth clearance before committing the BOM line.
Each main contact — both normally-open and normally-closed — is rated 40 A. That is the thermal current (Ith) at 40 °C ambient; for motor loads you derate to the AC-3 rating (not listed here, but typically around 18–22 A for an S2 frame). The auxiliary circuit also carries a 6 kV rated impulse withstand voltage. The coil holds at 24 V 50 Hz; dropout is not specified but typical for this class is around 0.7 × rated voltage.
The magnet coil connection is screw-type as well. Solid wire capacity: 2x (0.5... 1.5 mm²), 2x (0.75... 2.5 mm²), max. 2x (0.75... 4 mm²). Stranded wire: 2x (0.75... 25 mm²). AWG for main contacts: 2x (18... 2). That covers most panel wiring up to 25 mm² stranded — enough for a 40 A feeder. Side-by-side mounting is allowed, which saves rail space when you gang multiple contactors. The mounting position allows vertical surface with +/-180° rotation and +/-30° tilt front/back.
