Product details

It mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, and the mounting position allows ±180° rotation on a vertical surface plus ±22.5° tilt forward/backward — useful when fitting into tight gland-plate layouts or existing busbar arrangements.

The 24 V DC coil pulls 6 A at rated voltage, with a pickup dropout range of 0.8 to 1.1 times the rated value — so the coil holds reliably down to about 19.2 V and drops out below 18 V. AC-4 duty (plugging/inching) is limited to 250 ops/h. No built-in auxiliary switch, so if you need N.O./N.C. feedback for a PLC or safety circuit, you'll add a side-mount block. The main contact wire range accepts solid or stranded 1–10 mm², with a separate pair of terminals for 2x (0.5–2.5 mm²) — enough for the coil and auxiliary wiring without doubling up on the power terminals.

Frequently asked questions

Where can I buy 3RT2026-2BB44-3MA0 and get a price?

This part is sourced to order against an RFQ through independent distribution. Submit an RFQ for current availability and pricing — no stock count or price is published here.

What is the depth of 3RT2026-2BB44-3MA0?

The depth is 154 mm. That's the dimension from the DIN-rail mounting surface to the front of the contactor — important for enclosure depth planning.

What wire sizes does the spring terminal accept?

The main contacts accept solid or stranded wire from 1 mm² up to 10 mm². A separate pair of terminals handles 2x (0.5–2.5 mm²) for coil and auxiliary wiring.
