Record notes
Technical context to review before RFQ.
Siemens 3TK2821-1CB30 is maintained as a safety relay for machine-safety service, guarding circuits, and safety spare review.
It is grouped with SIRIUS / 3TK safety relay records so buyers can compare like-for-like spares instead of treating it as an anonymous import line.
The card is treated as rich because source-backed structured data supports the identity and specification depth. Current structured facts include compatible system Siemens machine safety relay family protection rating IP40
temperature range -25 ... +60 C series 3TK. USD price context is available as a reference observation, while final commercial terms still require RFQ confirmation.
Before approval, confirm safety rating, reset or monitoring logic, connector or wiring details, circuit drawing, quantity, preferred condition, and destination country.
The record does not claim verified channel relationship, confirmed allocation, warranty, lead time, or final compatibility without operations review.
