Clearance distances are tight: 50 mm above and below, 10 mm at the sides — no extra gap at 240 V, but at 400 V you need 160 mm above, 125 mm at 500 V, and 100 mm at 690 V.
Termination and ratings
Main circuit terminals are screw-type, accepting 2x 1–35 mm² or 1x 1–50 mm² solid or stranded copper. The M6 main contact bolts are standard for this frame size. Rated operational voltage spans 20 to 690 V. Maximum switching frequency in AC-3 duty is 15 operations per hour — fine for a pump or conveyor start, not for a jogging application.
