It carries 3 normally-open and 1 normally-closed pole, with a 240V AC 50Hz coil, rated for operational voltages up to 690V. This is the go-to part when you need a straightforward, field-serviceable relay for a machine control cabinet — no special tools, no programming, just wire it in and it runs.
The utilisation categories AC-14 and AC-15 tell you this relay is meant for electromagnetic loads — contactor coils, solenoid valves, small control transformers. AC-14 covers loads with a power factor around 0.3 (typical for contactor coils), while AC-15 handles the higher inrush of electromagnets. If you're switching resistive loads, the AC-1 rating would apply, but that's not what this part is specced for — stay in its lane and it'll last. The 3000 m altitude rating without derating means it's fine for high-altitude installations — no need to oversize for thin air. Mechanical robustness is decent: it stays closed through 10 Gn shocks for 11 ms, and open through 7 Gn. Vibration tolerance is 3 Gn closed, 1.5 Gn open across 5-300 Hz. That's enough for most industrial machinery, but not for direct mounting on a vibrating conveyor frame — if it's going on a shaker, isolate the panel.
The IP2X protection means it's finger-safe but not sealed — no washdown, keep it inside the panel. Terminal marking and wiring follow the standard control relay layout. The 3 NO + 1 NC contact arrangement is common enough that a wireman can land it without the diagram. Coil is 240V AC 50Hz — verify your control transformer matches before you energize.
It also meets GB/T 14048.1 and GB/T 14048.5 for the Chinese market. The TH protective treatment per IEC 60068 means it's treated against tropical humidity — relevant if the panel ships to a coastal or high-humidity site.
