The Schneider CAD32BDTQ is a TeSys Deca auxiliary contactor — a control-circuit relay rated for DC-13 duty, meaning it switches DC solenoid and electromagnetic loads. Its 3 NO + 2 NC pole arrangement gives you three normally-open and two normally-closed contacts in a single 45 mm wide package. The 24 V DC standard coil includes a bidirectional peak limiting diode for suppression, so you don't need an external flyback diode across the coil.
DC-13 is the utilisation category for switching solenoids, electromagnetic brakes, and clutches — the load type you'll find on valve banks and brake coils in material handling. The coil drops out at 0.1 to 0.25 Uc (2.4 to 6 V DC) and picks up reliably at 0.7 to 1.25 Uc (16.8 to 30 V DC), so a 24 V nominal supply with 10% ripple is fine. Mechanically linked contacts per IEC 60947-5-1 mean the NO and NC poles cannot both be closed simultaneously — a safety requirement for feedback circuits on guard monitoring.
The CAD32BDTQ carries approvals under 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. Impulse withstand is 6 kV. The TH protective treatment per IEC 60068 means it handles tropical environments — condensation and humidity in non-climate-controlled panels.
Terminals accept 1 to 4 mm² solid or flexible wire, or two 1 to 2.5 mm² with ferrules. Tightening torque is 1.7 N·m. The IP2X finger-safe front cover meets VDE 0106. Operating temperature range is -40 to 70 °C at nominal coil voltage, derated to -5 to 60 °C at 0.8 to 1.1 Uc. Storage range is -60 to 80 °C.
