What this contactor is and where it fits
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. It is designed for switching loads in control panels and is mounted via screw or snap-on onto 35 mm DIN rail per DIN EN 60715. The spring-type terminals accept solid or stranded conductors from 0.5 to 4 mm², and the contactor has no built-in auxiliary switch.
Key ratings and what they mean for your application
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.
Mounting and clearance
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. The mounting position allows ±180° rotation on a vertical surface and ±22.5° tilt forward/backward. These clearances are important for heat dissipation and arc containment.
