It is a 3-pole (3P) device rated for AC-3 duty at 12 A up to 440 V, meaning it is sized for reversing motor loads like conveyors, fans, or pumps where direction change is needed. The 24 VDC coil keeps control voltage consistent with modern PLC or safety relay outputs. The AC-4 and AC-1 utilisation categories are also listed, so it handles inching/jogging (AC-4) and resistive loads (AC-1) within its thermal current limits.
The IP20 finger-safe enclosure (per VDE 0106) means it is suitable for enclosed control panels where accidental contact is prevented by the cabinet door. Flame retardance meets UL 94 V1 and NF F 16-101/102, which matters for rail and transit applications.
Mechanical robustness and environmental sealing
The contactor is tested to IEC 60068-2-27 for shock and IEC 60068-2-6 for vibration. It withstands 15 Gn shocks when closed (11 ms) and 10 Gn when open, on the Z axis. Vibration resistance is 4 Gn closed, 2 Gn open, across 5–300 Hz. This makes it suitable for applications near rotating machinery or on mobile equipment. Protective treatment per IEC 60068 and DIN 50016 adds corrosion resistance in humid or mildly aggressive atmospheres. Storage temperature from -50 to 80 °C covers cold warehouses or hot shipping containers.
