It is a control-circuit relay — meaning it switches pilot devices, contactor coils, solenoid valves, and signal lamps in a panel, not motor power directly. Rated for utilisation categories AC-15 (inductive loads above 72 VA), AC-14 (solenoid loads below 72 VA), and DC-13 (solenoid loads with parallel diodes), it covers the typical control-voltage switching duties inside a 690 V line. The 5 NO contact arrangement gives you five independent make contacts on a single relay body — useful for spreading a start signal across multiple starters or PLC inputs.
The operating temperature range of -40 to 60 °C (with derating up to 70 °C) and storage range of -60 to 80 °C cover most indoor industrial environments, including unheated warehouses. Mechanical robustness is specified for shock and vibration: the relay stays closed through 15 Gn shocks (11 ms) and open through 10 Gn, and it withstands vibration of 4 Gn closed and 2 Gn open across 5–300 Hz. This means it holds its state under moderate machine vibration — think conveyor drives or pump skids — without chatter. The altitude rating of 0–3000 m covers most installations outside high-altitude mining or mountain-top sites.
The CAD50AP7 carries compliance with 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 control-circuit device standards for Europe, North America, China, and Japan. The TH protective treatment per IEC 60068 confirms it is tropicalized against humidity and corrosion for use in warm, damp climates.
