Product details

SIRIUS S00 power contactor with spring terminals

The Siemens 3RT2015-2FB44-3MA0 is a SIRIUS S00 power contactor rated for 24 V DC coil voltage, with a rated current of 6 A at 24 V DC. The contactor is designed for screw and snap-on mounting onto 35 mm DIN rail per DIN EN 60715, and its mounting position allows ±180° rotation on a vertical surface plus ±22.5° tilt forward/backward.

Duty-cycle and switching frequency

Maximum switching frequency depends on the duty class: 1 000 operations per hour at AC-1 (resistive load), 750/h at AC-2 and AC-3 (motor starting/running), and 250/h at AC-4 (plugging/inching). The AC-3e rating also allows 750/h.

The contactor has no auxiliary switch block, so any auxiliary contacts must be added separately.

Frequently asked questions

What is the closest functional second-source for 3RT2015-2FB44-3MA0?

The closest functional peer is 3RT2036-1AC20-ZX95, but it is a larger frame (S2 vs S00) with different coil voltage and terminal style. The 3RT2015-2FB44-3MA0 is a S00 frame with a 24 V DC coil and spring terminals; the 3RT2036-1AC20-ZX95 will not drop into the same panel footprint without rewiring and resizing the DIN rail space.

Where can I buy 3RT2015-2FB44-3MA0?

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 depth of 3RT2015-2FB44-3MA0?

The depth is 121 mm.

What solid conductor size does 3RT2015-2FB44-3MA0 accept?

It accepts solid conductors from 0.5 to 4 mm² (2x per terminal).
