Product details

It is rated for AC-3 motor switching at up to 750 operating cycles per hour, and the coil draws 6 A at 24 VDC under DC-13 duty — a figure that governs the sizing of the control transformer or DC supply feeding it.

The S0 footprint measures 45 mm wide, 102 mm tall, and 154 mm deep — the depth dimension is the one to watch when the panel backplate is tight against an enclosure wall or a second row of components.

Clearance and wiring

The main circuit accepts solid or stranded conductors from 1 to 10 mm²; the coil terminals accept 2x (0.5 to 2.5 mm²) solid or stranded. Spring-type terminals mean no screw torque to verify, but the wire strip length and ferrule selection (if using ferruled stranded) need to match the spring cage spec — per the datasheet, solid or ferruled stranded within the listed cross-section range.

Switching frequency and duty class

Maximum switching frequency depends on the duty class: 1 000 cycles/hour for AC-1 resistive loads, 750 cycles/hour for AC-2 and AC-3 motor loads, 750 cycles/hour for AC-3e, and 250 cycles/hour for AC-4 (plugging/reversing). The arcing time per the datasheet is 10 to 10 ms — a narrow window that suggests consistent arc extinction across the rated range. Mechanical life is listed at 10 000 000 operating cycles typical.

Frequently asked questions

Where can I buy 3RT2026-2FB44-3MA0 and how do I get a price?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

What is the depth of 3RT2026-2FB44-3MA0?

The depth is 154 mm, which is the dimension to check when the panel backplate is tight against an enclosure wall or a second row of components.

What conductor cross-section does the main circuit accept?

The main circuit accepts solid or stranded conductors from 1 to 10 mm². The coil terminals accept 2x (0.5 to 2.5 mm²) solid or stranded.

What compliance documentation does Siemens provide for this contactor?

The evidence does not list specific compliance documentation (RoHS, REACH, UL, IEC) for this order code. Standard Siemens SIRIUS contactors typically carry CE, UL, and CSA certifications, but confirm the specific declarations for this variant at time of order.
