The CAD50AFD: Rated for utilisation categories AC-15, AC-14, and DC-13 per EN/IEC 60947-5-1. AC-15 covers solenoid-valve and electromagnetic-brake loads above 72 VA; AC-14 covers electromagnetic loads below 72 VA; DC-13 covers solenoid loads with an inductive time constant. For a 110 V DC coil relay, DC-13 is the relevant category — it confirms the contacts can break DC inductive loads typical of contactor coils and small solenoids in a control panel. Storage range is -60 to 80 °C. The TH protective treatment per IEC 60068 means the relay is suitable for humid environments without conformal coating — common in unheated enclosures or washdown areas. Mechanical robustness is specified for shock and vibration: 10 Gn for 11 ms (relay open) and 15 Gn (relay closed), plus vibration at 2 Gn (open) and 4 Gn (closed) across 5–300 Hz. This makes it suitable for mounting on panels near vibrating machinery like pumps or compressors.
The IP2X front-face protection (VDE 0106) means the front is finger-safe, suitable for open-front panels or enclosures with a transparent door. Snap-in terminals accept up to 2.5 mm² wire, matching typical control-circuit wiring in a motor control centre.
Compliant 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. This covers the major global markets: IEC for Europe/Asia, UL/CSA for North America, GB/T for China, and JIS for Japan. Operating altitude is rated to 3000 m without derating.
