The GS1AF33 mounts directly onto the TeSys GS fuse-switch disconnector and provides instantaneous signalling when a fuse blows. Its 1 C/O contact (one normally-open and one normally-closed) gives a single changeover signal that can be wired to a PLC input or indicator lamp. Rated for 16 A switching current and 30000 electrical cycles under AC-15 load conditions, the contact is sized for control-circuit duty rather than main power switching.
Applications
This auxiliary contact is used in motor control centres and distribution panels where TeSys GS fuse-switch disconnectors protect branch circuits. It reports a blown fuse condition back to the control system, enabling remote fault indication without opening the panel door.
