The CAE31B6 is a control relay from the Schneider Electric Easy TeSys range, configured with 3 normally-open and 1 normally-closed pole contacts. It switches control circuits at up to 690 V, with a 24 V AC coil. The utilisation category is AC-14 and AC-15, meaning it is rated for electromagnetic loads typical of contactor and relay coils in control panels — not for heavy motor starting. Mechanical robustness is specified: the relay withstands 7 Gn shocks for 11 ms in the open position and 10 Gn closed; vibration tolerance is 1.5 Gn open and 3 Gn closed across 5–300 Hz. This is sufficient for most industrial panel environments but not for extreme mobile or high-shock applications. Altitude derating is not required up to 3000 m.
It also meets GB/T 14048.1 and GB/T 14048.5 for the Chinese market. Protective treatment is TH conforming to IEC 60068, which covers tropical heat and humidity conditions.
