Lifecycle status is active per Siemens — this isn't an NRND or obsolete line. RoHS compliant since June 2013, with REACH candidate-list disclosure available on request. The product class is B (return restricted), so if you're a panel builder or MRO planner, factor that into your RMA planning: returns need Siemens partner coordination, not a straight RMA.
Snaps onto standard DIN rail — 4-pole width means four modular spaces in the enclosure.
Group code P310 and product group 3822 are Siemens internal cataloguing — useful if you're cross-referencing against a legacy BOM or a Siemens parts portal. Export controls are AL:N / ECCN:N, so no regulatory friction for international procurement.
