The Schneider Electric CAE22R5 is an Easy TeSys control relay with a 2 NO + 2 NC contact configuration, designed for switching control circuits in industrial panels. It carries a 440 V AC 50 Hz coil and is rated for utilisation categories AC-14 and AC-15, meaning it's built for switching electromagnetic loads like contactor coils and solenoid valves — the kind of duty you see in starter and control schemes. The relay meets EN/IEC 60947-1, EN/IEC 60947-5-1, GB/T 14048.1, and GB/T 14048.5 standards, with IP2X finger protection per IEC 60529. It operates from -20 to 70 °C and stores from -60 to 80 °C, with no derating needed up to 3000 m altitude. Mechanical robustness is rated for 7 Gn shock when open and 10 Gn when closed, plus 1.5 Gn vibration open and 3 Gn closed across 5–300 Hz.
If you're trying to fill a legacy panel without re-engineering the wiring, the CAE22R5's 45 mm width and DIN-rail footprint mean a modern Easy TeSys relay with the same contact arrangement and coil voltage may drop into the same slot — but the coil voltage and contact configuration need to match exactly. No need to gut the whole line if you can source the original part or a direct-fit equivalent.
The AC-14 and AC-15 utilisation categories tell you this relay is meant for switching electromagnetic control loads — contactor coils, solenoid valves, brakes — not resistive heaters or motors directly. The 2 NO + 2 NC pole arrangement gives you two normally-open and two normally-closed contact sets, which covers most interlocking and auxiliary contact needs in a motor starter circuit. The 440 V AC 50 Hz coil is specific: if your control voltage is 400 V or 415 V at 50 Hz, it'll pull in fine, but a 480 V 60 Hz supply may push the coil outside its rated band. Dimensions are 74 mm high, 45 mm wide, and 80 mm deep — a standard compact relay footprint that fits alongside contactors on a DIN rail. The grey RAL 7011 housing is typical for control relays in Schneider's Easy TeSys range.
