Who knows old CB? 1

Hi everyone,

Anybody knows where I could find the TCC of a ST-TE3 trip unit (on a ST-TE 600 V, 1 600 A, 50 kA breaker)?

Data collection was made live, so that is all the information I could find...

Here is a picture...

Is it an obsolete Merlin Gerin breaker?
What I really need is the TCC.

Anyone?

It looks like Merlin-Gerin. Try your local Square D sales office.

I have some tcc curves here. Let me know if you still need them.

First of all, thank you

The Schneider local tech gave me the TCC.

FYI, ST-TE3 trip unit is in fact a ST-CM3 trip unit on a ITE breaker.
