Product details

The 3RT2018-2BB41-Z W97: The auxiliary contact configuration is 1 NO, spring-loaded terminals. The S00 frame size occupies a compact DIN-rail footprint, typically 45 mm wide, so plan panel layout accordingly.

RoHS compliant since October 1, 2009. REACH candidate list information is available per Article 33.

Mounts on DIN rail (standard EN 60715). The S00 frame allows side-by-side mounting without derating at 40 °C ambient; above that, consult the thermal derating curve. Spring-loaded terminals accept 0.5–2.5 mm² solid or ferruled stranded wire; strip length 8 mm. No separate coil suppression is built in; add a free-wheeling diode across the coil if driven by a PLC output.

Frequently asked questions

What compliance documentation is available for this contactor?

The contactor is RoHS compliant since October 1, 2009. REACH Article 33 duty-to-inform information is available upon request. Export control classification is AL: N / ECCN: N, meaning no special export licensing is needed for standard shipments.

What does the AC-3e/AC-3 rating mean for my motor application?

The AC-3e/AC-3 rating at 16 A and 7.5 kW at 400 V defines the contactor's capability for switching 3-phase induction motors: it can handle the high inrush current during starting and break the motor's running current. This is the standard duty class for motor switching in industrial control panels.

How is this part packaged for ordering?

This variant comes in multi-unit packaging with 32 units per pack. It is intended for panel builders or MRO buyers who need multiple contactors for a BOM line or stock replenishment.
