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.","metaTitle":"Siemens 3RT2015-2KB42-ZX95 SIRIUS Coupling Contactor, 24 V,","metaDescription":"Siemens SIRIUS 3RT2015-2KB42-ZX95 coupling contactor, size S00, 24 V coil, 10 A rated, spring-type terminals, screw and snap-on DIN rail mount.
