What this part is and where it fits
The Siemens 3RT1016-1AV02-ZX95 is a SIRIUS power contactor in frame size S00, designed for switching motor loads in control panels. It mounts via screw or snap-on onto a 35 mm DIN rail per EN 50022, so it integrates directly into a standard panel layout without adapters. Rated for 4 kW at 400 V under AC-2 duty (slip-ring motor starting) and 5.5 kW at 690 V, this contactor handles the common European 400 V three-phase motor range up to about 5.5 kW. The AC-4 rating of 8.5 A at 400 V covers plugging and inching applications where the motor is reversed or jogged under load.
Key ratings and what they mean for your circuit
The AC-12 rating of 10 A maximum operating current covers resistive and solid-state loads in control circuits — useful for feeding a PLC output or a small heater bank. The auxiliary contact block handles 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V, 6 A at 230 V, and 3 A at 400 V, so you can match the contact rating to your control voltage without oversizing. Short-circuit coordination is specified: with type 2 coordination, use a gL/gG fuse rated 20 A; with type 1 coordination, a 35 A gL/gG fuse. This lets the panel builder select the right upstream protection to avoid contactor damage under fault. The operating temperature range of -25 to +60 °C and pollution degree 3 mean it is suited for industrial environments with conductive dust or humidity, not just clean control rooms. Altitude limit is 2 000 m without derating.
Mounting and wiring in the panel
Width is 45 mm, height 57.5 mm, depth 72 mm — a compact footprint for the S00 frame. Side-by-side mounting is permitted with zero side clearance (6 mm to grounded parts), so you can pack multiple contactors on a DIN rail without spacing gaps. Main circuit terminals are screw-type, accepting 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²) solid or stranded wire. AWG equivalents are 2x (20 to 16), 2x (18 to 14), or 1x 12. The front and terminal faces carry IP20 finger protection, safe for open-panel work.
Lifecycle and sourcing reality
For a BOM line or a line-down replacement, the 3RT1016-1AV02-ZX95 is a direct fit into any panel designed for the S00 frame size. No rewiring or mounting changes needed if swapping from another S00 Siemens contactor with the same terminal arrangement.
