It provides four normally-open (4 NO) poles for switching control circuits, with a rated operational voltage up to 690 V and a 440 V AC coil. Rated for utilization categories AC-15 and AC-14 per EN/IEC 60947-5-1, so it handles the inductive loads typical of contactor coils, solenoid valves, and small motor starters in control panels. The 4 NO configuration means all four contacts close when the coil is energized — common for interlocking or multi-circuit enable signals. Mounts on a DIN rail (45 mm wide, 74 mm tall, 80 mm deep), fitting standard enclosure layouts alongside contactors and terminal blocks. IP2X protection means it's finger-safe but not sealed; keep it inside a panel away from washdown.
The 440 V AC coil voltage is the control voltage that pulls the relay in — common in 400 V three-phase panels where the control transformer feeds the coil directly. Make sure your control circuit matches that voltage; a 24 V DC coil version would be a different order code. Rated operational voltage up to 690 V covers most low-voltage industrial systems. The 4 NO contacts are rated for AC-15 duty, which means they can switch inductive loads. Environmental specs: operates from -20 to 70 °C, stores from -60 to 80 °C, and works at altitudes up to 3000 m without derating. TH treatment per IEC 60068 means it's protected against humid, tropical conditions — fine for most indoor industrial environments. Mechanical robustness: the relay stays closed under 10 Gn shocks and 3 Gn vibrations (5–300 Hz) — enough for most machine-mounted panels, but verify if your application has high-impact cycling.
That covers most global installations except where UL/CSA listing is specifically required — the evidence doesn't list UL or CSA marks, so confirm with your local code if needed.
