Product details

The Schneider Electric TeSys GS2AF74 is an auxiliary contact block designed specifically for blown-fuse signalling on GS1 and GS2 fuse switches. It carries a switch rated current of 1250 A and mounts to fuse holders accepting DIN NFC fuse links of size 4. Contact configuration is 1 C/O (one changeover) with instantaneous operation. The rated operational current varies by duty: 12 A at 24 V DC-13, 4 A at 230 V AC-15, 3 A at 400 V AC-15, and lower ratings for higher DC voltages. Conventional free air thermal current is 16 A at 40 °C.

The GS2AF74 snaps onto the back of GS1 or GS2 fuse switch disconnectors in a panel. The 1 C/O contact signals a blown fuse condition to a PLC input or indicator lamp.
