The contact configuration (3 NO + 2 NC) is built for control-circuit switching: the NO poles handle start/run signals, the NC pair serves interlock or status feedback. Rated operational voltage covers ≤690 V AC and 250 V DC, which covers most 24 VDC to 480 VAC control loops in industrial panels. Utilisation categories AC-15, AC-14, and DC-13 tell you what loads it can switch reliably. AC-15 covers solenoid valves and contactor coils — the high inrush a relay sees when energising an inductive control load. AC-14 is for electromagnetic devices with lower inrush. DC-13 covers DC solenoids and clutches. The relay is rated for control-circuit duty, not motor power switching.
The CAD32AUD carries 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 control-circuit device standards across Europe, North America, China, and Japan. That means it is accepted in panels destined for IEC or UL 508A shops without a separate component-level evaluation. TH protective treatment per IEC 60068 covers tropical/humid environments. The front face carries IP2X finger protection per VDE 0106.
Environmental limits and mounting
Storage range is -60 to 80 °C. Operating altitude is 0 to 3000 m — fine for most panel installations up to high-altitude sites. The 45 mm width matches a standard 2.5-module DIN-rail footprint; depth is 93 mm, height 107 mm. Mechanical robustness is specified for shock and vibration: 10 Gn for 11 ms when open, 15 Gn when closed; vibration 2 Gn open, 4 Gn closed across 5–300 Hz.
