Product details

It mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, with a mounting position that allows +/-180° rotation on a vertical surface and +/-22.5° tilt forward/backward — useful for tight enclosure layouts. The coil accepts 48 to 80 VDC, with pickup at 0.8x rated value and dropout below that; inrush current peaks at 1 A.

The S2 frame size and 55 mm width are the first fit check: this contactor occupies a standard 55 mm wide DIN-rail footprint. The arcing time of 10–20 ms and switching rates (700 ops/h at AC-1, 500 ops/h at AC-3, 150 ops/h at AC-4) tell you the thermal duty cycle — AC-4 (plugging/inching) derates the contactor significantly, so plan the application accordingly.

Frequently asked questions

Where can I buy the 3RT2038-1NE30 and how is it quoted?

The 3RT2038-1NE30 is sourced and quoted to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at the time of quote.

What are the key dimensions of the 3RT2038-1NE30?

Depth is 130 mm, width is 55 mm, and height is 114 mm. Clearance requirements: 10 mm upwards, downwards, and forwards; 6 mm at the sides.

Will the 3RT2038-1NE30 drop into a panel specified around a 3RT2015-1BW42?

Not directly. The 3RT2038-1NE30 is a size S2 contactor with a 55 mm width, while the 3RT2015-1BW42 is a smaller frame. Panel cutouts, DIN-rail space allocation, and terminal wiring patterns differ between the two sizes; rewiring and possibly re-drilling the mounting plate would be required.
