Product details

The 24 VDC coil pulls in at 10 A inrush per the datasheet, holding steady at the rated voltage.

Duty ratings and switching frequency

AC-3 motor switching is rated at 21 A at 480 V, which covers most 10–15 hp three-phase induction motors in that voltage class. AC-1 resistive load rating reaches 40 A at 400 V. Maximum switching frequency varies by duty: 1000 cycles/hour for AC-1, 750 cycles/hour for AC-2 and AC-3, and 250 cycles/hour for AC-4 (plugging or inching). The AC-3e rating matches the standard AC-3 figure at 750 cycles/hour.

The S0 frame occupies 45 mm width on the rail.

Frequently asked questions

Where can I buy 3RT2026-1AD00 and how is it quoted?

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

Will 3RT2026-1AD00 drop into a panel specified for 3RT2016-1AG62?

The 3RT2016-1AG62 uses a different coil voltage — 24 VAC versus the 24 VDC coil on this part. The S0 frame and DIN footprint are identical, but the coil supply must match. No rewiring of the power circuit is needed, but the control circuit requires a DC source.

What is the depth of 3RT2026-1AD00?

The depth is 97 mm from the mounting surface to the furthest projection.

What conductor sizes does the screw terminal accept?

Solid or stranded conductors from 1 to 10 mm². For two conductors in parallel, the terminal accepts 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²).
