It's the go-to for switching motor loads up to 4 kW at 690 V (AC-3 duty) or resistive loads up to 10 A at 24 V in control panels. The screw-type terminals on both main and auxiliary circuits accept 2x (0.5 to 1.5 mm²) solid or 2x (0.75 to 2.5 mm²) stranded, with a max of 2x (0.75 to 4 mm²) — so it handles standard panel wiring without adapters.
Ratings that matter for the BOM line
The 3RT1015-1AV61's AC-3 motor-switching capability is what most buyers need to confirm: 3 kW at 400 V, 3.5 kW at 500 V, and 4 kW at 690 V — so it covers standard 400 V three-phase motors up to about 4 kW (roughly 5.5 HP). The coil holds at 24 VDC nominal, and the contactor is rated for 30 million mechanical operations, so it'll outlast the machine in most cycling applications.
The Size S00 footprint is 45 mm wide by 57.5 mm tall by 72 mm deep — it tucks into tight DIN-rail rows. The screw terminals are clearly marked and accept AWG 20–14 for main and auxiliary circuits (2x conductors per terminal). For Type 1 coordination, use a 35 A gL/gG fuse upstream; for Type 2, a 20 A gL/gG fuse limits fault energy to protect the contactor. That's a real time-saver during panel design — no guessing the fuse size.
