Product details

Integrator's note: 3RT1015-1BD41

It switches motor loads up to 4 kW at 690 V AC-3, or 3.5 kW at 500 V. The coil draws 3.3 W both closing and holding, so the control transformer can be sized for a continuous 3.3 W load per contactor.

Side-by-side mounting is permitted with 6 mm spacing to adjacent devices, which keeps the gland plate fill factor manageable. Screw-type terminals on the main circuit accept 2x (0.5 to 1.5 mm²) solid or 2x (0.75 to 2.5 mm²) stranded, up to 2x 4 mm² max. AWG equivalents are 2x (20 to 16) solid, 2x (18 to 14) stranded, or 1x 12.

Ratings and coordination

For AC-2 duty at 400 V, the contactor is rated at 3 kW; for AC-4 at 400 V, it handles 6.5 A. The auxiliary contact block includes one normally-open instantaneous contact.

Frequently asked questions

What is the closest functional second-source for 3RT1015-1BD41?

The 3RT1015-1BB42 is a direct peer in the same SIRIUS S00 frame, but with a 24 VDC coil instead of 42 VDC. The mechanical footprint, terminal layout, and power ratings are identical, so it drops into the same panel without rewiring — only the coil voltage differs.

Where can I buy 3RT1015-1BD41?

This part is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm commitment.

What is the depth of 3RT1015-1BD41?

The depth is 72 mm, which fits standard shallow enclosures and leaves room for wiring behind the DIN rail.

What wire sizes does the 3RT1015-1BD41 accept?

The screw terminals accept 2x (0.5 to 1.5 mm²) solid, 2x (0.75 to 2.5 mm²) stranded, or up to 2x 4 mm² maximum. AWG equivalents are 2x (20 to 16) solid, 2x (18 to 14) stranded, or 1x 12.
