The CAD32ACD is a TeSys Deca control relay from Schneider Electric, built for switching control circuits — the logic side of the panel, not the motor power legs. It carries 3 normally-open and 2 normally-closed contacts (3 NO + 2 NC), a 36 V DC standard coil, and is rated for operational voltages up to 690 V. The utilisation categories tell you what loads it can handle: AC-15 for solenoid valves and electromagnetic clutches, AC-14 for contactor coils, and DC-13 for DC solenoids and contactors. These are the control-circuit duty classes from IEC 60947-5-1 — if your load is a small motor starter coil or a pilot lamp, this relay is sized for it. The 36 V DC coil matches standard control voltages in many industrial DC bus architectures. Mechanical robustness is specified: the relay withstands 10 Gn shocks for 11 ms when open, 15 Gn when closed, and vibration up to 4 Gn at 5–300 Hz in the closed state. That means it stays latched under the vibration you'd expect near a large compressor or a reciprocating pump skid.
Standards and approvals — regulatory reach
The CAD32ACD is certified to 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. That covers the major industrial markets: IEC for global, UL/CSA for North America, GB for China, JIS for Japan. The front face carries IP2X protection per VDE 0106, meaning it's finger-safe from the front when panel-mounted.
Dimensions are 45 mm wide, 107 mm high, 93 mm deep — a standard compact footprint for a 5-pole control relay. Snap-in terminals speed wiring: the spring-cage style accepts solid or ferruled stranded conductors. Operating temperature range is -40 to 60 °C, with derating up to 70 °C; storage range is -60 to 80 °C. Altitude rating goes to 3000 m without derating. Protective treatment is TH conforming to IEC 60068, meaning the relay is treated for tropical heat and humidity — relevant if the panel sits in a non-conditioned environment or near a washdown zone.
