Overview
The GS1AM4 is an auxiliary early-break and signalling contact for the Schneider TeSys GS 630...1250 range of fuse-switch disconnectors, switching 12 A through its 4 C/O contact set.
Selection vs GS1AM3
Compared to the GS1AM3, which carries 3 C/O contacts, the GS1AM4 adds a fourth C/O pole — a meaningful difference when the control circuit needs an extra early-break signal without adding a second contact block.
Availability
Schneider lists the GS1AM4 as active; no end-of-life notice applies, and standard lead times apply through distribution.
