Accepts solid or stranded wire from 1 to 10 mm² (2x per clamp) and AWG 18 to 8 for the main contacts. The magnet coil also terminates with spring-type terminals, so the control wiring is tool-less as well. The coil is rated 24 V DC and includes a built-in diode combination surge suppressor — no external flyback diode needed on the PLC output. ## Lifecycle and sourcing No stock-holding claim — quoted per RFQ.","metaTitle":"Siemens 3RA2327-8XB30-2FB4 SIRIUS reversing contactor","metaDescription":"Siemens 3RA2327-8XB30-2FB4 SIRIUS reversing contactor assembly, S0 size, 15 kW at 400 V AC-3.
