Product details

The GS1AF34 is an auxiliary contact from the Schneider TeSys GS range, designed as a blown-fuse signalling contact for GS1 and GS2 fuse switches. It carries a 160 A switch rated current and provides one changeover (1 C/O) contact set across 4 poles. The fuse accommodation is DIN NFC type, size 0.

Rated operational currents (Ie) vary by duty: 12 A at 24 V DC-13, 4 A at 230 V AC-15, 3 A at 400 V AC-15, 2 A at 48 V DC-13, 0.6 A at 110 V DC-13, and 0.4 A at 220 V DC-13. These are the contact ratings for signalling circuits, not main power switching — the AC-15 and DC-13 categories cover electromagnetic loads typical of contactor coils and solenoid valves.

Durability and integration

Rated for 30,000 cycles mechanical and 30,000 cycles electrical under AC-15 duty. Contact operation is instantaneous — no time-delay built in. The 1 C/O contact arrangement provides one normally-open and one normally-closed set sharing a common terminal, suitable for remote blown-fuse indication in a panel.

Frequently asked questions

What is the closest alternative to the GS1AF34?

No official successor order code is listed. A form-fit-function evaluation against current TeSys GS auxiliary contacts is needed to identify a suitable replacement, as the fuse size 0 and DIN NFC fuse type are specific to the GS1/GS2 platform.

What are the key ratings for the GS1AF34?

Switch rated current is 160 A. Conventional free-air thermal current (Ith) is 16 A at 40 °C. Rated operational currents include 4 A at 230 V AC-15 and 12 A at 24 V DC-13, among other duty-specific values.

What is the fuse size and type for this auxiliary contact?

The GS1AF34 is designed for DIN NFC fuse type, size 0.
