Star-delta starter, pre-assembled and wired
The 3RA2426-8XE32-2BB4: It ships with three contactors: 3RT2027-2BB40-0CC0, 3RT2027-2BB40, and 3RT2026-2BB40, plus the 3RA2923-2BB2 RS assembly kit — everything needed for a wye-delta start circuit in one order code.
Wiring and protection details that matter
Both main and control circuits use spring-loaded terminals — no screw torque to check, just strip and push. Siemens specifies fuse protection at 50 A using gG NH 3NA, DIAZED 5SB, or NEOZED 5SE types — coordinate the upstream protection with this rating, not the motor FLA.
