It provides 3 normally open and 1 normally closed instantaneous contacts, rated 10 A at 24 V, 6 A at 230 V, and 1 A at 690 V. That makes it a signal-level or low-power load interface inside a panel, not a motor starter. Size S00 (45 mm wide, 57.5 mm high, 72 mm deep) fits the standard DIN-rail footprint. Fastening is screw and snap-on mounting — drops onto a 35 mm rail with a clip, no tools needed for the rail, screws for the wires.
Contact ratings — the so-what
The 10 A at 24 V rating is the highest continuous current; at 110 V it drops to 1 A, and at 230 V it's 6 A. At 690 V it's 1 A. These are AC switching values — the contactor is built for control circuits, not motor inrush. The 3 NO + 1 NC arrangement gives you one extra NC for a feedback or interlock, which is common in safety or sequencing logic. If you're switching PLC-level signals at low voltage, this contactor handles it without the oxide-film problems that plague power contacts.
Screw terminals accept solid conductors: 2x 0.5–1.5 mm², 2x 0.75–2.5 mm², or 2x 4 mm². That covers most control-circuit wiring up to 12 AWG.
