Product details

It mounts on 35 mm DIN rail per DIN EN 50022 via screw or snap-on fastening, fitting into standard panel layouts with a footprint of 130 mm depth, 65 mm width, and 114 mm height.

Switching Ratings and Duty Cycle

Rated for 6 A at both 24 V and 230 V AC, with a drop to 3 A at 400 V and 0 A at 690 V — the contactor is sized for low-to-medium voltage capacitor banks, not motor switching. Maximum switching frequency is 100 operations per hour at 230 V and 400 V, derating to 30 per hour at 690 V — relevant for frequent cycling in harmonic filter stages.

The magnet coil uses screw-type terminals. Solid conductor capacity covers 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), and 2x 4 mm². Stranded connections accept 2x (10 to 35 mm²) or 1x (10 to 50 mm²). At 40 °C ambient, a single 35 mm² conductor is sufficient; at 60 °C, step up to 50 mm² for the same current path.

Frequently asked questions

Where can I buy 3RT2636-1AP05 and how is it quoted?

This part is sourced to order against an RFQ through independent industrial distribution. Availability and current pricing are confirmed at quote time — no stock count or price is shown here.

Will 3RT2636-1AP05 drop into a panel specified around 3RT2536-1AP00?

Both are S2 frame capacitor contactors with the same DIN rail mounting and similar dimensions, but the evidence does not list a direct interchange. Verify the termination scheme and coil voltage before substituting without rewiring.

What is the depth of 3RT2636-1AP05?

The depth is 130 mm, with a width of 65 mm and height of 114 mm.
