Product details

The 24 VDC coil pulls in at 85% of rated voltage (20.4 V) and holds reliably; the spring-type terminals accept 0.5 to 4 mm² solid or stranded wire, so no screwdriver torque check on the line — just strip, insert, release. The contactor mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, and the mounting position allows ±180° rotation on a vertical surface plus ±22.5° tilt forward/backward — useful when you're squeezing it into a crowded gland plate.

Dimensions: 45 mm wide, 70 mm high, 121 mm deep — the depth is the dimension that sticks out from the DIN rail, so check your enclosure depth if you're retrofitting into a shallow gland plate. That's tight enough for most standard enclosures, but the forward clearance means you need room for the spring terminals and wiring loop.

Switching performance and duty ratings

Maximum operating frequency varies by duty: 1,000 cycles/hour at AC-1 (resistive), 750 cycles/hour at AC-2 and AC-3 (motor starting/running), and 250 cycles/hour at AC-4 (plugging/inching).

Frequently asked questions

What is 3RT2016-2WB41's listed depth on this component line?

The depth is 121 mm, measured from the DIN rail mounting surface to the front of the contactor. That's the dimension to watch when fitting into a shallow enclosure.

What wire sizes does the spring terminal accept?

The spring-type terminals accept solid or stranded wire from 0.5 to 4 mm², including 2x (0.5 to 4 mm²) for paralleled conductors.

Will 3RT2016-2WB41 drop into a panel that was specified around 3RT2015-1BW42 without rewiring?

Both are S00 frame contactors with the same mounting footprint on 35 mm DIN rail, so the mechanical swap is straightforward. The 3RT2016-2WB41 uses spring terminals versus screw terminals on the 3RT2015-1BW42, so you'll need to re-terminate the wiring — no screwdriver needed, but the wire preparation (strip length, ferrule if stranded) must match spring-clamp practice.
