This is the variant with a varistor built into the surge suppressor — it clips the coil's turn-off spike so you don't need an external snubber on the PLC output.
At 690 V it's rated 48 kW, which is the motor power it can switch in AC-3 duty (squirrel-cage induction motors, starting and stopping under load). Derate for higher ambient: at 60 °C the same 690 V circuit still handles 159 kW — that's the thermal margin in the S6 frame. At 400 V and 60 °C it's good for 92 kW. The insulation voltage is rated 1000 V, so it lives comfortably in 690 V panels without creeping.
Mechanical fit and panel integration
Footprint is 172 mm high by 120 mm wide, 170 mm deep. Screw fixing to the mounting plate. Mounting position is vertical surface, rotatable ±90° and tiltable ±22.5° front-to-back.
Switching frequency and coil data
Rated switching frequency is 2000 operations per hour for both AC and DC control circuits. Maximum mechanical switching rate hits 10,000,000 operations typical for the contactor itself — that's the mechanical life, not the electrical endurance under load. AC-1 resistive load maximum is 800 ops/h; AC-3 motor load max is 1000 ops/h; AC-4 (plugging/inching) max is 130 ops/h. Coil pick-up at 24 V draws 6 A inrush; at 110 V it's 1 A; at 220 V it's 0.3 A; at 230 V it's 6 A again; at 400 V it's 3 A.
