Control Relay for Control Circuit Switching
The Schneider Electric TeSys CAD32AT7 is a control relay from the TeSys Deca series, designed for control circuit applications. It provides 3 normally open (NO) and 2 normally closed (NC) contacts, rated for operational voltages up to 690 V. The 480 V AC standard coil makes it a direct fit for many North American and global panel designs running 480 V control transformers. Rated for utilisation categories AC-15, AC-14, and DC-13 per EN/IEC 60947-5-1, this relay is built for switching solenoid loads, electromagnetic clutches, and contactor coils — the typical loads in a control cabinet. The AC-15 rating specifically covers switching of electromagnetic loads above 72 VA, which is the dominant duty for a relay driving other contactors or relays downstream.
With a 45 mm width and 107 mm height, the CAD32AT7 fits standard DIN-rail mounting alongside other TeSys Deca components. The IP2X front-face protection (conforming to VDE 0106) means it is touch-safe on the front of the panel but expects enclosure protection for the wiring side — standard for a panel-mounted control relay. Rated for operation from -40 to 60 °C (with derating up to 70 °C) and storage from -60 to 80 °C, it handles unheated warehouses and outdoor cabinet installations. The TH protective treatment per IEC 60068 confirms it is suitable for humid environments without condensation — a common requirement for panels in washdown areas or coastal plants. Mechanical robustness is specified: the relay withstands 10 Gn shocks for 11 ms when open, 15 Gn when closed, and vibrations of 2 to 4 Gn across 5 to 300 Hz. This makes it suitable for installation on machinery with moderate vibration profiles, such as conveyor drives or compressor skids.
Standards and Compliance Coverage
The CAD32AT7 carries compliance 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. This covers the major global markets — Europe (IEC/EN), North America (UL/CSA), China (GB/T), and Japan (JIS) — so it can be specified into export panels or multi-site projects without requalification.
