The GS1AF73 is an auxiliary blown fuse signalling contact from the TeSys GS range, configured as a 1st C/O changeover contact for 3-pole fuse holders rated up to 1250 A. It mounts directly onto the TeSys GS fuse switch disconnector base, providing a remote electrical indication when the fuse element has blown — a key signal for motor control centres and distribution panels where a blown fuse must trigger an alarm or inhibit reclosure.

Frequently asked questions
What is the closest alternative to GS1AF73?
No official successor order code is published. A functionally equivalent auxiliary contact from the same TeSys GS family would need to be selected based on the same 1st C/O configuration and 1250 A rating, but the exact mounting and wiring interface should be verified against the existing fuse switch base.
