The Schneider Electric CAE40M5 is an Easy TeSys Control Relay with four normally open (4NO) contacts, designed for switching control circuits in industrial panels. Its utilisation categories — AC-14 and AC-15 — mean it is certified for switching electromagnetic loads typical of contactor coils, relays, and solenoid valves in control circuits, per EN/IEC 60947-5-1. The AC-15 rating is the more demanding one, covering loads with high inrush (up to 10× steady-state), so this relay handles the inductive kick from a contactor pull-in without welding its own contacts.
The grey (RAL 7011) housing is standard for the Easy TeSys range, so it integrates visually and mechanically alongside other TeSys control gear in a panel. The 4NO contact arrangement is typical for signalling or interlocking multiple loads from a single control signal. Mechanical robustness is specified for vibration (1.5 Gn open, 3 Gn closed, 5-300 Hz) and shock (7 Gn open, 10 Gn closed, 11 ms), so it holds its state under the jolt of a nearby contactor closing or a conveyor start.
