What the ratings mean for your panel
The 3RT1016-1AV02-ZW95: The 24 VDC coil holds at nominal voltage, typical for PLC-driven panels where 24 V is the control bus standard. The AC-3 rating of 5.5 kW at 690 V tells you the contactor can handle standard three-phase induction motors up to that power; the AC-4 rating of 8.5 A at 400 V covers reversing or jogging duty where the contactor makes and breaks motor current under load. For resistive or heating loads, the AC-12 rating of 10 A is the ceiling. Type 1 coordination calls for a 35 A gL/gG fuse upstream; type 2 coordination uses a 20 A gL/gG fuse. That's the short-circuit protection the contactor needs to survive a fault without welding its contacts — size the branch circuit fuse accordingly.
DIN rail mounting and panel fit
Mounts via screw or snap-on onto 35 mm standard rail per DIN EN 50022. The S00 footprint is 45 mm wide by 57.5 mm tall by 72 mm deep — compact enough for dense panels. Side-by-side mounting is permitted (no derating gap needed), which saves rail space when ganging multiple contactors.
Termination and wiring
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/stranded. AWG equivalents: 2x (20 to 16), 2x (18 to 14), or 1x 12. Front and terminal protection is IP20 — finger-safe for panel installation, but not for washdown environments.
