The CAD32AE7 is a TeSys Deca control relay from Schneider Electric's active-production TeSys family — 3 NO + 2 NC pole configuration, 48 V AC 50/60 Hz standard coil, snap-in terminals for panel wiring. It is a control-circuit relay, not a power contactor: the utilisation categories tell you exactly what loads it can switch. AC-15 covers solenoid valves and electromagnetic clutches (inductive loads above 72 VA). AC-14 covers small contactor coils (below 72 VA). DC-13 covers solenoids with parallel diodes. On a 48 V AC control transformer, this relay handles the pilot-duty switching a PLC or pushbutton station demands — rated operational voltage up to 690 V on the contacts. The 3 NO + 2 NC contact arrangement gives you three normally-open and two normally-closed poles. In a typical control scheme, the NO poles handle the main enable or run signal; the NC poles provide a feedback or interlock path. Snap-in terminals mean the relay clips directly onto a DIN rail without tools — no mounting screws, just a spring clip and a screwdriver for the wiring. The front face carries IP2X protection per VDE 0106, so finger-safe against accidental contact inside an enclosed panel. Storage range is -60 to 80 °C. Altitude limit is 0 to 3000 m — above that, dielectric and thermal margins start to compress. The relay carries TH protective treatment per IEC 60068, meaning it is tested for tropical heat and humidity environments without condensation.
The CAD32AE7 is certified to EN/IEC 60947-5-1 (control-circuit devices), UL 60947-5-1, CSA C22.2 No 60947-5-1, GB/T 14048.5, and JIS C8201-5-1. That means it is accepted for panel builds in Europe, North America, China, and Japan without a separate approval step. For a BOM freeze, these standards cover the device-level safety and switching performance; the UL and CSA marks are the ones US and Canadian inspectors look for on the nameplate.
