The Schneider TeSys GS1AV33 is a fuse cover interlock kit — a locking accessory that prevents access to the fuse compartment while the circuit is live. It belongs to the TeSys range of control and protection components, and is rated for 160 A across three poles. This is not a standalone fuse holder or disconnect switch; it is the interlock cover that mounts onto a compatible TeSys GS fuse base. The interlock mechanism ensures the cover cannot be opened when the switch is in the ON position, enforcing a basic safety sequence for maintenance access.
What the 160 A rating means for fit
The 160 A rating is the system current the interlock kit is designed to accompany — it matches the ampere rating of the TeSys GS fuse switch it covers. In practice, this means the interlock is sized for a 160 A three-pole fused disconnect, so if your BOM calls for a 160 A TeSys GS switch, this is the correct interlock cover. A lower- or higher-rated switch would use a different interlock part.
