The auxiliary switch is rated at 6 A at 24 V DC, 2 A at 48 V DC, 2 A at 60 V DC, 1 A at 110 V DC, and 0.9 A at 125 V DC — these are the DC-13 switching limits for the built-in contact, not the main pole ratings. Verify your auxiliary load against these curves before committing the BOM line. ## Duty cycle and thermal limits Maximum operating cycles per hour vary by duty: 500/h for AC-1, AC-3, and AC-3e; 200/h for AC-2; 130/h for AC-4; 250/h for DC-1, DC-3, and DC-5. Screw fixing with one 11 mm diameter hole. Accepts solid or stranded wire: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), max 2x (0.75 to 4 mm²).
