The Schneider Electric CAE22B5 is an Easy TeSys control relay with a 24 V AC 50 Hz coil and 2 NO + 2 NC pole contact composition. Rated operational voltage goes to 690 V, and it's listed for utilisation categories AC-15 and AC-14 — meaning it's built for switching electromagnetic loads (contactors, solenoids) and resistive loads at moderate currents in control circuits.
This relay occupies a 45 mm wide footprint on the DIN rail, 74 mm tall and 80 mm deep — a standard control-panel slice that leaves room for adjacent terminal blocks or a smaller contactor. Ambient operating temperature spans -20 to 70 °C, which covers most ventilated enclosures; storage range is -60 to 80 °C. It's rated for operation up to 3000 m altitude without derating, so it's fine for high-altitude installations or unpressurised cabinets in mountainous sites. Mechanical robustness is specified for vibration at 1.5 Gn (contacts open) and 3 Gn (contacts closed) across 5–300 Hz, with shock tolerance of 7 Gn open and 10 Gn closed — enough for machine-mounted enclosures on pumps or conveyors without nuisance drop-out.
Compliant with EN/IEC 60947-1 and EN/IEC 60947-5-1, plus the GB/T equivalents 14048.1 and 14048.5. The IP2X degree of protection (per IEC 60529) means it's finger-safe — no live parts accessible through the enclosure — which is standard for DIN-rail control gear. Protective treatment is TH conforming to IEC 60068, covering tropicalised humidity resistance for warm, damp environments.
