Product details

What It Is & What It Does

The 24 VDC coil pulls in at 0.8 of rated voltage and drops out at 1.1 of rated voltage — standard pickup/dropout margins for this class.

Rated operational current is 6 A at 24 V — that's the continuous current the main contacts carry at that coil voltage. For motor duty (AC-3), it's rated for 750 switching cycles per hour maximum; for resistive loads (AC-1), up to 1000 cycles per hour. The arcing time is a tight 10 ms, which limits contact erosion during break.

Mounting & Clearances

That 6 mm side gap is tight — factor it into your DIN rail layout if you're stacking multiple contactors.

Terminal Capacity & Mechanical Life

For the coil terminals, use 2x (0.5 to 2.5 mm²) solid or stranded.

Environmental Range

The storage range is wider than the operating range — that's typical for handling and warehousing, not for running the coil at those extremes.

Frequently asked questions

What are the key dimensions of this contactor?

Width is 45 mm, height is 102 mm, depth is 154 mm. That depth includes the spring-type terminal protrusion — account for it when sizing your enclosure depth.

What wire sizes does the 3RT2026-2BB44-ZX95 accept?

Main contacts accept 1 to 10 mm² solid or stranded. Coil terminals accept 2x (0.5 to 2.5 mm²) solid or stranded. Spring-type terminals on the coil — no screw torque needed.

How does this compare to the 3RT2026-1FB44-3MA0?

The 3RT2026-1FB44-3MA0 is a sibling in the same S0 frame size, but it uses screw-type terminals on the main contacts rather than spring-type. If your panel is already wired for screw terminals, the 1FB44 variant drops in without retooling your lugging process. The 2BB44's spring terminals save wiring time but require a ferrule for stranded wire below 1 mm².
