The contact ratings are specified per voltage: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 1 A at 690 V. These are thermal current ratings for the auxiliary contacts — they define the continuous current the contacts can carry at each voltage level, not the motor load. For a 24 VDC control loop, the 10 A rating gives ample headroom for pilot devices and PLC inputs; at 690 V, the 1 A limit governs signal isolation in higher-voltage auxiliary circuits.
Mechanical endurance and contact reliability
The 6 kV rated surge voltage withstand (impulse) ensures the contacts survive transient overvoltages common in industrial control panels.
Mounts in any orientation on a vertical surface, with ±180° rotation and ±22.5° tilt permitted. Shock resistance is 10g for 5 ms and 5g for 10 ms.
