Part identity and mounting position
The GS1ANT11G is a TeSys GS1AN auxiliary contact block — 1 NC + 1 NO instantaneous contacts — designed for right-side mounting on GS2 switch-disconnectors that carry an external left-side operating handle with test position signalling. It reports O, I, and test position status back to the control circuit.
Rated operational current — what the duty codes mean for your control circuit
The Ie ratings are duty-specific: 10 A at 230 V AC-15 (solenoid/contactor coil loads), 12 A at 127 V AC-15, 6 A at 440 V AC-15, and 8 A at 400/415 V AC-15. For DC control circuits it carries 1 A at 220 V DC-13, 4 A at 48 V DC-13, and 1.2 A at 110 V DC-13. The conventional free-air thermal current Ith is 20 A at 40 °C — that is the thermal limit for continuous current through the contact block in open air, not the switching capacity.
Durability and fuse coordination
Electrical durability is rated 30,000 cycles under AC-15 duty; mechanical durability matches at 30,000 cycles. The fuse type is listed as DIN BS NFC — meaning the block coordinates with gG/gL fuses per DIN / BS / NFC standards for short-circuit protection. This matters for selectivity studies and panel label coordination.
