Part overview and lifecycle
The CAE31M6 is a control relay from the Easy TeSys range, configured with 3 normally open and 1 normally closed pole contacts. It carries a 220 V AC coil and is rated for operational voltages up to 690 V. This part is now obsolete per the manufacturer's lifecycle status.
Rated for utilisation categories AC-14 and AC-15, this relay is suited for switching electromagnetic loads in control circuits — think contactor coils, solenoid valves, and small motor starters where the inrush current can be several times the sealed current. The AC-15 rating specifically covers inductive loads above 72 VA, which is the typical territory for a panel's control transformer secondary. The 3 NO + 1 NC contact arrangement gives you three independent make contacts for pilot devices or PLC inputs, plus one break contact for an interlock or status feedback. Mechanical robustness is documented: the relay withstands 7 Gn shocks for 11 ms when open and 10 Gn when closed, with vibration resistance of 1.5 Gn open and 3 Gn closed across 5–300 Hz. That's enough for most industrial cabinet installations, including those near moderate vibration sources like conveyor drives or small compressors.
Standards and environmental limits
Compliant with EN/IEC 60947-1 and EN/IEC 60947-5-1, plus the Chinese equivalents GB/T 14048.1 and GB/T 14048.5. The TH protective treatment per IEC 60068 indicates it's built for tropical/humid environments. Operating temperature spans -20 to 70 °C, storage from -60 to 80 °C, and it runs without derating up to 3000 m altitude.
