Part identity and ratings
The CAD32AK7 is a TeSys Deca control relay from Schneider Electric's established TeSys range, configured with 3 normally-open and 2 normally-closed pole contacts. It is rated for control-circuit applications across utilisation categories AC-15, AC-14, and DC-13 — meaning it is specified for switching solenoid loads, electromagnetic brakes, and contactor coils, not power circuits.
Standards and environmental limits
Compliant with EN/IEC 60947-5-1, UL 60947-5-1, CSA C22.2 No 60947-5-1, GB/T 14048.5, and JIS C8201-5-1 — so the relay is accepted in European, North American, Chinese, and Japanese installations without additional certification work. The front face carries IP2X finger protection per VDE 0106, adequate for enclosed panels where operators reach in for manual reset. Operating temperature spans -40 to 60 °C, with derating required above 60 °C up to 70 °C; storage range is -60 to 80 °C. Altitude rating to 3000 m covers most industrial sites outside high-mountain installations.
Mechanical and environmental robustness
Rated for 10 Gn shock (11 ms) when open and 15 Gn when closed, with vibration resistance of 2 Gn (open) and 4 Gn (closed) across 5-300 Hz per IEC 60068-2-27 and IEC 60068-2-6. Protective treatment TH conforming to IEC 60068 means the relay is treated against tropical humidity — a practical detail for installations in warm, damp environments like textile mills or food-processing areas where condensation is routine.
