The 3 NO + 3 NC auxiliary contacts are built in, covering the typical feedback and control logic for a star-delta transition without an add-on auxiliary contact block. The spring-type (cage-clamp) terminals on Size S0 accept solid or ferruled stranded wire without retightening — a time saver in panel build and less prone to thermal cycling loosening than screw terminals. ## Deployment context — panel integration for wye-delta motor starting The spring terminals reduce wiring time and eliminate screw-torque verification during FAT. The integrated mechanical interlock prevents both the main and delta contactors from closing simultaneously, which is the primary failure mode in a star-delta start — a welded contactor on one side cannot pull in the other. The electrical interlock adds a second layer through the NC auxiliary contacts in the coil circuit.","metaTitle":"Siemens 3RA2423-8XF32-2BB4-ZA01 Star-Delta Starter","metaDescription":"Siemens SIRIUS 3RA2423-8XF32-2BB4-ZA01 star-delta contactor assembly, 11 kW at 400 V AC-3, 24 V DC coil, Size S0, spring terminals, 3 NO+3 NC.
