The CAE31R5 is a control relay from the Easy TeSys range, built for switching control circuits in industrial panels. Its contact arrangement is 3 normally open plus 1 normally closed, rated for utilisation categories AC-15 and AC-14 — meaning it handles solenoid and electromagnetic loads typical of contactor coils, valves, and small motors in control logic. The coil is wound for 440 V AC 50 Hz. Rated operational voltage goes up to 690 V, and the relay carries approvals to EN/IEC 60947-1, EN/IEC 60947-5-1, GB/T 14048.1, and GB/T 14048.5. It operates from -20 to 70 °C and can be stored from -60 to 80 °C. Altitude rating is 3000 m without derating. Mechanical robustness is specified: 7 Gn shock when open, 10 Gn when closed; vibration resistance of 1.5 Gn open and 3 Gn closed over 5–300 Hz.
This part is marked obsolete by the manufacturer. If you are holding a last-time-buy window or a line-down situation, we can check availability on the secondary market.
AC-14 is a lighter inductive load class. Together they cover most 24–440 V AC control circuits in a panel. Dimensions are 45 mm wide, 74 mm high, 80 mm deep — a standard compact footprint for DIN-rail mounting in a control cabinet. The grey RAL 7011 housing is typical for the Easy TeSys family.
