The CAD32AFD is a TeSys Deca control relay with a 3 normally-open plus 2 normally-closed pole configuration, rated for control-circuit duty. The 110 V DC coil is standard — no rectifier module needed on the coil terminals. Snap-in terminals reduce wiring time on a DIN-rail assembly, and the IP2X front-face protection (per VDE 0106) means accidental finger contact during panel access is prevented. Utilisation categories AC-15 (solenoid/contactor control above 72 VA) and DC-13 (solenoid control with inductive loads) tell you this relay handles the inrush and switching duty of pilot devices and contactor coils in a control panel. Rated operational voltage up to 690 V covers most 400/480 VAC control circuits with headroom. Operating temperature range of -40 to 60 °C (with derating to 70 °C) and storage from -60 to 80 °C suit it for unheated electrical rooms or outdoor-rated enclosures in moderate climates. Altitude rating to 3000 m is typical for standard industrial installations — no derating needed at most plant elevations.
Standards and approvals for global BOMs
The CAD32AFD carries 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 certifications. That covers acceptance in IEC markets, North America (UL/CSA), China (GB), and Japan (JIS). The protective treatment TH conforming to IEC 60068 means it resists humidity and corrosive atmospheres — relevant for coastal or chemically mild process areas. No NRND or obsolescence notice applies.
Mechanical robustness for vibration-prone mounts
Shock resistance: relay remains closed at 15 Gn for 11 ms, and open at 10 Gn for 11 ms (per IEC 60068-2-27). Vibration: 4 Gn closed, 2 Gn open over 5–300 Hz (per IEC 60068-2-6). These ratings mean the CAD32AFD holds its state under the vibration levels typical of motor-starter panels mounted on compressor skids or conveyor frames — it won't chatter open on a pump start.
Integration into a control panel
Dimensions: 45 mm wide, 107 mm high, 93 mm deep. The 45 mm width occupies three 15 mm modular spaces on a DIN rail — standard for a 5-pole control relay in the TeSys Deca family. Snap-in terminals accept the same fork or ring lugs as the TeSys contactors in the same row, keeping the wiring consistent across the panel.
