The 3 NO main contacts handle the load-switching path. At AC-2 duty under 400 V the contactor is rated for 4 kW, and at AC-4 under 400 V it carries 8.5 A — these are the duty-cycle ratings that govern motor switching, not the thermal continuous current. For resistive loads (AC-12) the maximum operating current is 10 A. The mechanical life of 10 million cycles means the contactor is rated for high-frequency switching applications such as conveyor or pump cycling. The coil pulls 24 V at 50 Hz with a tolerance factor of 0.8 to 1.1 — so the coil holds in reliably between 19.2 V and 26.4 V. Side-by-side mounting is permitted with 6 mm spacing to adjacent devices.","metaTitle":"Siemens SIRIUS 3RT1023-1AB04-ZX95 Power Contactor, 3 NO, S0,","metaDescription":"Siemens SIRIUS 3RT1023-1AB04-ZX95 power contactor.
