It's rated for control circuit duty under utilisation categories AC-15 and AC-14, meaning it's built for switching electromagnetic loads like contactor coils and solenoid valves, as well as resistive loads at voltages up to 690 V. The 4 NO pole composition gives you four independent switching channels, all closing when the coil is energised. The AC-14 category covers electromagnetic loads with lower inrush, such as small solenoids. Both ratings are per EN/IEC 60947-5-1, which is the standard for control-circuit devices. The 4 NO contact arrangement is fixed — there are no changeover (CO) or normally closed (NC) contacts in this unit, so if your circuit needs a break contact, this relay won't fit without external wiring workarounds. Mechanically, the CAE40B5 is rated to withstand 7 Gn shocks when open and 10 Gn when closed, plus vibration up to 3 Gn at 5–300 Hz in the closed position. That puts it in the range for panel-mounted use in industrial environments with moderate machine vibration — think conveyor lines or pump skids, not high-impact presses. The IP2X finger-protection rating means the relay body prevents access to live parts with a finger-sized probe, which is standard for enclosed control panels but not sufficient for open or washdown locations. Operating temperature spans -20 to 70 °C with storage from -60 to 80 °C, and it runs without derating up to 3000 m altitude. The TH protective treatment per IEC 60068 indicates the relay is treated for tropical humid environments, which is useful if the panel sees condensation or high relative humidity. The CAE40B5 is designed and tested to EN/IEC 60947-1 and EN/IEC 60947-5-1, plus the Chinese equivalents GB/T 14048.1 and GB/T 14048.5.","metaTitle":"Schneider Electric CAE40B5 Easy TeSys Control Relay, 4NO, 24","metaDescription":"Obsolete control relay from Schneider Electric Easy TeSys series. 4 NO contacts, 24V AC 50Hz coil, AC-15/AC-14 rated.
