It carries three normally-open main contacts and is rated for a 220 V 60 Hz coil supply.
For motor switching duty, the 3RT1016-1AN11 is rated at 4 kW at AC-2 at 400 V, meaning it handles wound-rotor motor starting and reversing loads up to that power. At AC-4 at 400 V, the rated operational current is 8.5 A, which covers plugging and inching duty for squirrel-cage motors within that current envelope. The coil draws its rated supply at 220 V 60 Hz, with an operating range of 0.8 to 1.1 times the rated value — so the coil holds in from 176 V to 242 V at 60 Hz. Short-circuit coordination is specified: type 2 coordination requires a gL/gG fuse rated 20 A, while type 1 coordination requires 35 A. This determines the upstream fuse sizing for the motor branch circuit.
Its width is 45 mm, height 57.5 mm, and depth 72 mm — a compact S00 footprint that fits standard DIN-rail enclosures. Side-by-side mounting is permitted, which means multiple contactors can be ganged on the rail without derating for heat dissipation — useful for compact motor starter assemblies. The enclosure offers IP20 protection on the front and at the terminals, meaning finger-safe but not protected against water ingress — suitable for dry indoor panel environments only.
Terminal details and wiring
Both main current circuit and auxiliary/control circuit terminals are screw-type. The main contacts accept solid or stranded conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or a maximum of 2x (0.75 to 4 mm²). AWG equivalents are 2x (20 to 16), 2x (18 to 14), or 1x 12. Auxiliary contact terminals accept the same conductor cross-sections as the main contacts.
Operating environment
The product carries a RoHS compliance date of 01.07.2006, indicating it meets the EU RoHS directive for restricted substances. The IEC 81346-2 reference code is Q, which designates switching devices in the standard designation system.
