The 24 V DC coil includes a plugged-in varistor for suppression. The auxiliary contact block carries 2 NO + 2 NC contacts, factory-integrated as a captive auxiliary switch. The AC-3 rating governs motor switching — starting and disconnecting induction motors under load. The 24 V DC coil is standard for PLC-driven panels; the varistor handles the back-EMF from the DC coil, so no external flyback diode is needed across the coil terminals. The captive auxiliary switch means the 2 NO + 2 NC block is physically locked to the contactor — it cannot be separated during maintenance, which keeps the auxiliary wiring intact when swapping the main contactor.","metaTitle":"Siemens 3RT2024-2DB44-3MA0 SIRIUS Contactor, 12 A, 24 V DC,","metaDescription":"Siemens SIRIUS 3RT2024-2DB44-3MA0 power contactor, AC-3e/AC-3 rated 12 A, 5.5 kW at 400 V, 24 V DC coil, 2 NO + 2 NC aux, spring-loaded terminals, size S0.
