The GS2AF64 is an auxiliary contact block from the Schneider Electric TeSys GS range, designed for blown-fuse signalling on GS1 and GS2 fuse switch disconnectors. It carries a single C/O contact set (1 C/O) and is rated for a switch rated current of 630 A. It mounts directly onto the fuse holder, and the contact operation is instantaneous — no delay built in. The fuse type is DIN NFC, size 3, meaning it mates with standard DIN rail-mount fuse bases of that footprint.
The rated operational currents (Ie) vary by duty: 4 A at 230 V AC-15 (solenoid/contactor control), 3 A at 400 V AC-15, 12 A at 24 V DC-13 (DC solenoid), 2 A at 48 V DC-13, 0.6 A at 110 V DC-13, and 0.4 A at 220 V DC-13. For a blown-fuse signalling contact, the AC-15 ratings are the ones that govern most panel applications — the contact is switching the coil of a remote indicator or PLC input, not a motor load.
Durability and approvals
Both electrical and mechanical durability are rated at 30,000 cycles — the same figure for AC-15 duty and for mechanical life, which is typical for an auxiliary contact block in this class. The part carries no specific UL/CSA/CE markings in the evidence, but as a TeSys GS component it is designed to meet IEC 60947-5-1 for control circuit devices. If a compliance certificate is needed for your panel build, request it with the RFQ.
