Auxiliary contactor for control-circuit switching
Its 42 V DC coil draws 3.2 W during both closing and holding, so the coil-supply sizing is straightforward — no inrush peak beyond the steady-state power.
Solid conductors up to 4 mm² (or 2x 2.5 mm²) terminate in the screw terminals — strip length and ferrule sizing follow standard practice for this terminal class.
Contact ratings and mechanical life
The three NO contacts are rated for 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, 2 A at 500 V, and 1 A at 690 V — these are the AC-15 / DC-13 utilization categories typical for auxiliary contactors switching solenoid valves, contactor coils, and indicator lamps. Shock resistance is 10g for 5 ms and 5g for 10 ms, adequate for most industrial machinery vibration profiles.
