The coil is 125 V DC, and the contactor includes one normally closed auxiliary contact. The utilisation categories cover AC-1 (resistive loads), AC-3 (squirrel-cage motors), and AC-4 (plugging/inching). For a reversing contactor, AC-4 duty is particularly relevant — it handles the high electrical stress during motor reversal without derating below the 12 A threshold at 440 V. The contactor is rated IP20 per VDE 0106, so it is suitable for installation inside an enclosure where fingers or tools are kept out.
Mechanical and environmental ratings
The contactor is rated for shock and vibration per IEC 60068-2-27 and IEC 60068-2-6: 15 Gn for 11 ms on Z axis when closed, 10 Gn when open. Vibration withstand is 4 Gn closed, 2 Gn open across 5–300 Hz. This makes it suitable for installation on machinery or in panels subject to moderate mechanical stress. Flame retardance is V1 per UL 94, and it also meets NF F 16-101 and NF F 16-102 requirements — relevant for rail or public-transport applications where fire safety is audited. Operating altitude is 2000 m without derating, which covers most industrial sites. Protective treatment is TC per IEC 60068 and DIN 50016, indicating a tropicalised coating for humid or corrosive environments.
