Lifecycle status is current production — no phase-out or last-time-buy notice on this order code. The 5SY7640-7 is an active catalog line within the SENTRON family, so it can be specified into new BOMs without an obsolescence risk horizon. Sourced to order against an RFQ through independent distribution; availability and current pricing confirmed at quote time.
Mounts in any position on 35 mm DIN rail via the quick-assembly system — no tools needed for snap-on. Depth is 76 mm (70 mm behind the panel face), which fits standard 80 mm deep enclosures. The combined top and bottom terminals accept Cu conductors; IP20 with conductors connected means it's protected against finger contact inside a closed panel but not against dripping water — keep it inside a rated enclosure. Sealable (padlockable toggle) for lockout/tagout compliance on the branch circuit. Halogen-free and silicon-free construction matters if this breaker lives in a clean room or near sensitive electronics where outgassing can cause contact corrosion.
