The CAE40N5 is a control relay from Schneider Electric's Easy TeSys range, built for switching control circuits in industrial panels. It carries four normally-open (4 NO) contacts, rated for operational voltages up to 690 V, with a 415 V AC 50 Hz coil. The utilisation category is AC-15 and AC-14, which means it's designed for switching electromagnetic loads like contactor coils, solenoids, and valves — the kind of inductive loads you find in a control cabinet. The AC-15 rating specifically covers loads with high inrush, so it handles the coil pick-up current without welding contacts.
The grey housing (RAL 7011) is IP2X finger-safe per IEC 60529, so it's fine for open-panel mounting where accidental contact is a concern. It's rated for operation from -20 to 70 °C ambient, with storage from -60 to 80 °C, and works at altitudes up to 3000 m without derating. The TH protective treatment per IEC 60068 means it's suitable for humid environments — no extra conformal coating needed for most panel conditions. Mechanical robustness is specified for vibration and shock: the relay stays closed under 3 Gn vibration (5-300 Hz) and open under 1.5 Gn, and withstands 10 Gn shock when closed, 7 Gn when open. That's enough for most industrial machinery, including conveyors and compressors mounted near the panel.
The CAE40N5 is compliant with EN/IEC 60947-1 and EN/IEC 60947-5-1, the core standards for control circuit devices and switching elements. It also meets GB/T 14048.1 and GB/T 14048.5 for the Chinese market.
