Part identity and what it does
The 3RT5064-6AR36: For the main circuit, it uses screw-type terminals, which is what you'd expect for a contactor this size — no spring-cage surprises when you're landing 120 or 150 mm² cable. Side-by-side mounting is allowed, so you can pack them tight on the DIN rail without derating for heat buildup.
Key ratings and what they mean for your panel
At 400 V and 60 °C ambient, this contactor handles 164 kW; at 690 V it's rated for 82 kW. That 690 V figure is important if you're on a 690 V line — common in mining or marine — because not every contactor in this frame size carries that rating. The 164 kW at 400 V tells you it's sized for big motor loads, not just distribution switching. The insulation voltage is rated at 1 000 V, and pollution degree 3 means it's designed for industrial environments where conductive dust or condensation might be present. The built-in surge suppressor uses a varistor — that's your coil protection sorted, no separate module to order.
Mounting and integration notes
Mounting is by screw fixing — not a snap-on DIN clip — so plan for a backplate or mounting rail with drilled holes. The contactor can be mounted on a vertical surface with +/-90° rotation and +/-22.5° tilt front-to-back, giving you flexibility in tight cabinets. Dimensions are 145 mm wide, 210 mm high, and 202 mm deep. That depth matters when you're fitting a gland plate or door-mounted HMI — make sure your enclosure depth clears 202 mm plus cable bending radius.
