What it is and where it fits
The 3RT6018-1AP01: Mounting is via screw and snap-on onto 35 mm DIN rail per DIN EN 50022, with a ±180° rotation possible on vertical surfaces and ±22.5° tilt forward/backward. The S00 frame keeps panel density high — 45 mm wide, 57.5 mm tall, 73 mm deep.
Key ratings and what they mean for your panel
Rated insulation voltage is 690 V, matching the maximum AC-3 / AC-3e switching voltage of 690 V. That means this contactor can switch a 400 V motor circuit with headroom — the 690 V rating is the insulation limit, not the operating recommendation, but it tells you the creepage distances are sized for 690 V systems. At 400 V and 60 °C ambient, the contactor is rated for 13 kW motor power. At 690 V and 60 °C, that rises to 22 kW. These are the derated figures — the panel builder should use the 60 °C column when the enclosure runs warm, not the 40 °C column. Mechanical life is typical 30 million operations. Electrical life depends on duty: AC-1 (resistive) allows up to 1,000 operations per hour, AC-3 (motor starting) up to 750 per hour, and AC-4 (plugging/inching) up to 250 per hour. The 10,000 1/h figure at AC is the no-load mechanical switching rate. Coil consumption is 0.25 A at both 50 Hz and 60 Hz at 230 V — a standard control transformer can drive it without oversizing. The coil holds at 24 V nominal (6 A inrush at that voltage) and drops out cleanly below the pick-up threshold.
Termination and wiring
Main current circuit uses screw-type terminals. Wire range accepts 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm² — solid or stranded. Minimum permissible cross-section at 40 °C is 4 mm², derating to 2.5 mm² at 60 °C. Side-by-side mounting is permitted without derating the thermal capacity.
