Active SIRIUS S0 — 8 A AC-3, snaps onto 60 mm busbars
The 3RA2120-1HH24-0BB4: It ships as a pre-assembled kit: the supplied contactor is 3RT2024-2BB40 and the link module is 3RA2921-2AA00 — no separate component matching needed.
Mounting and wiring — busbar snap-on, spring terminals
Designed for snapping onto 60 mm busbar systems — the mounting position is vertical, and the footprint is 165 mm deep by 45 mm wide by 260 mm tall, with 50 mm clearance upward and 20 mm forward. Main circuit wiring uses spring-loaded terminals — tool-less insertion for solid or ferruled stranded wire, which speeds panel assembly and reduces torque-check time.
Sourcing — active, quoted to order
Available through independent distribution; quantities are quoted against the BOM at RFQ, with current pricing and lead time confirmed at quote time.
