The CAD50AJ7 is a TeSys Deca control relay from Schneider Electric, built for switching loads in control circuits. It carries five normally-open (5 NO) pole contacts and a 12V AC standard coil, with a rated operational voltage up to 690V. The utilisation categories — AC-15, AC-14, and DC-13 — define its switching capability: AC-15 covers solenoid and electromagnetic loads above 72 VA, AC-14 handles smaller solenoid loads below 72 VA, and DC-13 is for solenoids with parallel diodes. That means this relay is sized for the inductive loads typical in contactor coils, valve actuators, and small motor starters, not resistive heating elements.
Ambient operating range is -40 to 60 °C, with derating allowed up to 70 °C, and storage from -60 to 80 °C. Altitude rating goes to 3000 m without derating.
The CAD50AJ7 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 core standards for control-circuit devices and switching elements. It also carries TH protective treatment conforming to IEC 60068 for tropical environments. Mechanical robustness is tested to 10 Gn shocks (relay open) and 15 Gn (closed), with vibration resistance at 2 Gn open and 4 Gn closed across 5-300 Hz.
