Product details

Coil and switching specs

The 3RT2017-2XB42-0LA2: The DC coil draws a 2.3 A inrush peak and holds at 10 A at 24 V rated value. Operating range is 24-34 V DC, with a dropout below the 0.7 initial value factor. Switching the coil takes 25-45 ms at DC; arcing time runs 10-15 ms. For AC switching, the contactor handles 3 A at 400 V, 11 A at 480 V, and 11 A at 600 V rated value.

Panel integration and clearances

The S00 frame measures 45 mm wide, 73 mm deep, and 70 mm high. The spring-type terminals accept 2x (0.5-1.5 mm²), 2x (0.75-2.5 mm²), or 2x 4 mm² solid or stranded wire.

Frequently asked questions

Where can I buy 3RT2017-2XB42-0LA2 and how is it quoted?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What are the key dimensions for panel layout?

The contactor is 45 mm wide, 73 mm deep, and 70 mm high. Minimum clearances are 10 mm upward, forward, and downward, and 6 mm at the side.

What wire sizes does the spring terminal accept?

The spring-type terminals accept 2x (0.5-1.5 mm²), 2x (0.75-2.5 mm²), or 2x 4 mm² solid or stranded conductors.

Will 3RT2017-2XB42-0LA2 drop into a panel specified for 3RT2015-1BW42?

Both are Size S00 contactors on the same 35 mm DIN rail footprint, so the mechanical fit is identical. The primary difference is the coil voltage: this part uses a 24-34 V DC coil, while the 3RT2015-1BW42 uses a different coil rating. Verify coil supply before swapping.
