The CAE22N5 is a Schneider Electric Easy TeSys control relay with a 2NO+2NC contact arrangement and a 415V AC 50Hz coil. It's built for control-circuit switching in panels — rated AC-15 and AC-14 utilisation categories per EN/IEC 60947-5-1, which means it's suited for solenoid valves, contactor coils, and similar inductive loads common in industrial control cabinets.
The 2NO+2NC contact set gives you two normally-open and two normally-closed poles, which covers most interlocking and signal-routing needs in a control panel without adding auxiliary contact blocks. The 415V AC 50Hz coil voltage is specific — confirm your control transformer matches that, because a 400V or 480V coil won't pull in reliably at 415V. The AC-15 rating means the contacts are rated for switching inductive loads like contactor coils up to their rated current; AC-14 covers electromagnetically-operated devices. TH treatment per IEC 60068 means it's protected against humid, tropical conditions — a plus for coastal or unconditioned plant rooms.
The grey RAL 7011 housing is the usual Easy TeSys colour, consistent across the series.
