Product details

The 24 VDC coil draws 8.4 VA at 50 Hz and 0.24 A at 60 Hz — a modest load that a standard 24 VDC power supply handles easily. The main contacts (NO and NC each rated 25 A) suit motor starting and general switching in a control cabinet. Screw terminals accept solid wire from 0.5 up to 4 mm² (2x 0.75–4 mm² max), so you can land standard motor and control wiring without crimping ferrules.

The S0 frame measures 85 mm high × 61 mm wide × 91 mm deep — fits in a standard 200 mm deep enclosure with room for wiring ducts. The mounting surface can be vertical, rotatable ±180°, and tiltable ±30° front/back.

Frequently asked questions

Where can I buy 3RT1526-1AD20 and get a price?

We source and quote this part to order against an RFQ. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

What is the depth of 3RT1526-1AD20?

The listed depth is 91 mm. Combined with 85 mm height and 61 mm width, it fits a standard 200 mm deep enclosure.

What wire sizes does the 3RT1526-1AD20 accept?

Screw terminals accept solid wire: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), and max 2x (0.75 to 4 mm²).

Will 3RT1526-1AD20 drop into a panel designed for 3RT2526-1AD20?

Both are S0-frame power contactors with screw terminals and 24 VDC coils, so the footprint and wiring are the same. The 3RT1526-1AD20 is the standard-duty version; the 3RT2526-1AD20 is a higher-rated variant. Check the coil current and contact ratings against your load before swapping.
