The Schneider Electric CAE22U5 is a control relay from the Easy TeSys range, designed for switching control circuits in industrial panels. It carries a 2NO+2NC contact configuration and a 240V AC 50Hz coil, rated for operational voltages up to 690V. This part is built to EN/IEC 60947-1 and EN/IEC 60947-5-1 standards, covering the mechanical and electrical endurance requirements for control-circuit switching.
The 2NO+2NC pole composition gives you two normally-open and two normally-closed auxiliary contacts — enough to handle a typical start/stop interlock with a feedback signal, or to mirror a contactor's auxiliary block in a smaller panel. The 240V AC 50Hz coil is a standard control voltage across European and Asian installations; verify your control transformer matches before wiring. The relay is rated for utilisation categories AC-14 and AC-15, which means it's suited for switching electromagnetic loads like contactor coils and solenoid valves — not resistive heating elements or DC circuits.
The grey (RAL 7011) housing is typical for Schneider control relays. Operating temperature range is -20 to 70°C, with storage from -60 to 80°C, and it can be installed at altitudes up to 3000 m without derating. The TH protective treatment per IEC 60068 means it's resistant to humidity and condensation in tropical environments — useful if the panel sees seasonal temperature swings.
