The Schneider Electric CAD323S7 is a TeSys Deca control relay with a 3 NO + 2 NC pole contact composition, rated for operational voltages up to 690 V and fitted with a 500 V AC standard coil. It's built for switching control circuits in industrial panels — think PLC outputs, contactor coils, solenoid valves, and signal interlocking where you need to break or make multiple paths with one command.
The utilisation categories are AC-15, AC-14, and DC-13. The 3 NO + 2 NC contact arrangement fits in a 45 mm wide package.
At 45 mm wide, 99 mm tall, and 84 mm deep, it occupies a standard 4-module DIN-rail footprint. The IP2X front-face protection (conforming to VDE 0106) means it's finger-safe from the front once installed in an enclosure — no extra cover needed for basic touch protection. Operating temperature range is -40 to 60 °C, with derating required above 60 °C up to 70 °C; storage range is -60 to 80 °C. It's TH-treated per IEC 60068 for tropical environments, so it handles humidity in non-climate-controlled cabinets.
This part is obsolete per the manufacturer's lifecycle status.
The CAD323S7 carries approvals under EN/IEC 60947-5-1, GB/T 14048.5, UL 60947-5-1, CSA C22.2 No 60947-5-1, and JIS C8201-5-1 — so it's accepted in European, North American, Chinese, and Japanese installations. Mechanical robustness is specified: 10 Gn for 11 ms shock (relay open), 15 Gn (relay closed); vibration at 2 Gn open, 4 Gn closed across 5-300 Hz. That's enough for most industrial machinery but not extreme mobile equipment.
