Product details

At 85 mm tall, it leaves room for auxiliary blocks on top.

The 24 VDC coil draws 5.4 W on close and hold — that's the same number, so no extra inrush heat to plan for. The S0 frame size tells you this is a compact contactor for moderate motor loads; it's not the smallest (S00) or the largest (S3) in the SIRIUS family. The IP20 front and IP00 terminal block mean it's meant for a closed panel, not a washdown floor. Pollution degree 3 confirms it handles conductive dust and occasional condensation — typical for industrial control cabinets.

This contactor switches motor loads in control panels — pumps, conveyors, fans, compressors. AC-4 at 400 V gives 15.5 A for reversing or inching duty. The side-by-side mounting clearance is 6 mm, so you can pack several on a DIN rail without derating, as long as you respect the fuse coordination: Type 2 requires a 35 A gL/gG fuse, Type 1 allows up to 100 A.

Frequently asked questions

Where can I buy 3RT1026-1BB40-0BA0-ZX95?

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

What is the listed depth of this contactor?

The depth is 101 mm, which fits standard 35 mm DIN rail enclosures with room for wiring.

What terminal wire sizes does it accept?

For solid wire, it accepts 2x (0.5–1.5 mm²), 2x (0.75–2.5 mm²), and up to 2x (0.75–4 mm²). For stranded, it takes 2x (1–2.5 mm²), 2x (2.5–6 mm²), and max 2x 10 mm². AWG equivalents are 2x (16–12), 2x (14–10), and 1x 8 for the main contacts.
