Product details

The Siemens 3RT2015-2KB42-ZX95 is a size S00 coupling contactor from the SIRIUS family, rated at 24 V coil voltage and 10 A at that rated value.

The 10 A rating at 24 V governs the DC switching capacity at that voltage; at 48 V it drops to 2 A, and at 400 V it is 3 A. The AC-3 maximum operating frequency is 750 cycles per hour, which suits motor switching in conveyor or pump duty. The mechanical life is typical 30 million operations, indicating a long service interval before replacement.

The contactor measures 45 mm wide, 70 mm high, and 73 mm deep. Minimum clearances: 10 mm upwards, downwards, and forwards; 6 mm at the side. These clearances are important for heat dissipation and arc containment.

Frequently asked questions

Where can I buy 3RT2015-2KB42-ZX95 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.

Will 3RT2015-2KB42-ZX95 drop into a panel specified around 3RT2015-2HB41 without rewiring?

Both are size S00 contactors with the same mounting footprint on 35 mm DIN rail, but the 3RT2015-2KB42-ZX95 uses spring-type terminals while the 3RT2015-2HB41 uses screw terminals. Rewiring may be needed if the panel was wired for screw-clamp terminations.

What compliance documentation does this brand provide for 3RT2015-2KB42-ZX95?

The SIRIUS brand typically provides RoHS, REACH, UL, and IEC declarations. Specific documentation is available on request.
