The CAD326BDS207 is a TeSys D control relay from Schneider Electric, built for switching control circuits in industrial panels. It carries 3 normally-open and 2 normally-closed contacts, rated for operational voltages up to 690 V, with a 24 V DC standard coil. This is the part you'd slot into a motor starter or contactor control scheme where you need auxiliary contact multiplication or logic interlocking.
The utilisation categories AC-14, AC-15, and DC-13 tell you this relay is rated for switching electromagnetic loads — contactor coils, solenoid valves, small motor starters — not resistive heaters. AC-15 and DC-13 are the standard categories for control-circuit inductive loads per IEC 60947-5-1. The 3 NO + 2 NC pole composition gives you five independent contact paths; common in star-delta or reversing starter schemes where you need one relay to handle both the main coil and the interlock. The -40 to 70 °C operating range covers unheated enclosures in cold climates and warm cabinet interiors near drives or transformers.
This relay carries EN/IEC 60947-4-1 and 60947-5-1, plus UL 60947-4-1 and CSA C22.2 No 60947-4-1 — so it's accepted in North American and European control panels without extra paperwork. It also meets EN 45545 R22 HL3 for fire behaviour on rail vehicles, and the TH protective treatment per IEC 60068 means it's tested for tropical humid environments. The UL 94 V-0 flame retardance and 850 °C glow-wire resistance (IEC 60695-2-1) add confidence for high-risk installations.
