The Schneider CAD50AT7 is a TeSys Deca control relay with five normally-open (5 NO) pole contacts, rated for operational voltages up to 690 V and fitted with a 480 V AC standard coil. The 5 NO configuration means it can switch five independent control circuits simultaneously — typical for interlocking multiple contactors or signalling a PLC input bank from a single command. The utilisation categories AC-15, AC-14, and DC-13 tell you it's rated for switching electromagnetic loads (contactors, relays) and resistive/inductive control circuits, not motor power directly. The 480 V AC coil is the standard voltage for North American 480 V control transformers; if your panel runs 400 V or 230 V, you'll need a different coil variant in the TeSys Deca family.
Depth is 93 mm, height 107 mm. Snap-in terminals accept ring or fork lugs; strip length and torque follow standard TeSys Deca practice.
The relay 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 — the global suite of control circuit device standards. That covers the electrical endurance, dielectric, and thermal-rise tests for switching control loads. The TH protective treatment (conforming to IEC 60068) means it's treated against tropical humidity and fungal growth, which matters for panels shipped to or operating in warm, humid environments. Operating temperature range is -40 to 60 °C (with derating up to 70 °C), and storage range is -60 to 80 °C — wide enough for most industrial enclosures.
