The GS1AV1 is a fuse cover interlock kit from the TeSys GS range, designed for 3- or 4-pole fuse holders accepting DIN/NFC size 00 fuses up to 63 A. It functions as a locking accessory — the cover interlock prevents opening the fuse compartment while the circuit is live, a standard safety requirement for panel builders and maintenance access.
This part is marked obsolete by the manufacturer. An RFQ is the practical next step to confirm availability and condition.
