It is rated 16 A at 250 V AC, 50 Hz, with 2 normally-open poles (2 NO). Control is via a 230 V AC impulse (50 Hz), minimum 50 ms duration, from a remote push-button or PLC output drawing 3 mA.
The 16 A rated current (In) at 250 V AC is the continuous thermal current the contacts can carry in resistive or general-use AC loads (AC-22 duty). Electrical durability is 200,000 cycles under AC-22 — that is the service life for switching resistive loads like lighting banks or heating elements. For motor or inductive loads, derate accordingly; the relay is not rated for AC-3 motor switching. The 2-pole configuration (2 NO) means both poles switch simultaneously, suitable for two-wire or two-phase circuits up to 250 V line-to-neutral.
Width is 18 mm (1 module), depth 69 mm, height 87 mm — fits a standard 1-module cutout in a distribution board. Terminals are tunnel type: power circuit accepts 1 to 4 mm² rigid or flexible (1 or 2 cables), control circuit 0.5 to 1.5 mm². Strip length 9 mm, tightening torque 1 N·m. IP20 on the opening (finger-safe), IP40 inside an enclosure — suitable for clean, dry indoor panels. Pollution degree 3 (industrial environment).
