QUESTION:
What is the purpose of 3SB1902-2AT, 3SB1902-2AU, 3SB1902-2AV Support terminals? What are these products supposed to be used for?

ANSWER:
3SB1902-2A. support terminals are designed like switching elements for base mounting and can be fitted the same way inside 3SB18 enclosures. The function is that of a through-type terminal. These support terminals facilitate the connection of potentials that don't have to be switched. Another possibility is the connection of diode elements.
