Terminals and Wiring
Main circuit connections use screw-type terminals. The solid wire range is 2x (0.25 to 2.5 mm²), and for stranded wire it accepts 2x (0.75 to 25 mm²). The minimum permissible copper cross-section at 40 °C is 16 mm², so plan your cable sizing accordingly for continuous current. Auxiliary contacts are rated for switching at various control voltages: 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V. That covers most PLC and relay logic outputs you'll find in a standard panel.
For compliance, the substance prohibitance date is listed as 05/01/2012, which aligns with RoHS and REACH requirements.
Mechanical Endurance and Switching Frequency
Typical mechanical life is 10,000,000 operations. Maximum switching rates vary by duty: 1,200 cycles per hour for AC-1 resistive loads, 1,000 for AC-3 motor starting, and 300 for AC-4 plugging duty. That's enough for most conveyor, pump, and fan applications. Side-by-side mounting is permitted, which helps when you're packing multiple contactors into a tight row on the DIN rail.
