The GS1AM111 is an auxiliary contact block from the Schneider TeSys GS1AM series, designed as a side-mount early-break contact for a GS1 32 A switch-disconnector with a direct frontal handle. It provides O and I position signalling — meaning it reports whether the main switch is open or closed, and the early-break contact opens before the main poles, which is useful for pilot circuits that must drop out ahead of the power circuit.
The contact block carries a 1 C/O (one changeover) configuration. The real-world switching capacity depends on the duty: in AC-15 (pilot duty for solenoid valves and contactor coils) it handles 5 A at 127 V, 4 A at 230 V, 3 A at 400/415 V, and 2 A at 440 V. For DC-13 (solenoid loads) it manages 12 A at 24 V, 2 A at 48 V, 0.6 A at 110 V, and 0.4 A at 220 V. The switch rated current of the main disconnector it mounts to is 32 A — the auxiliary block itself is not the main power path, but the 16 A Ith gives headroom for the signal circuit.
Mounting and integration note
Mounts on the right side of the GS1 32 A switch-disconnector. The direct frontal handle means the auxiliary block is actuated by the handle mechanism, not a separate linkage. In a panel, this clips onto the switch body and adds one C/O signal contact without increasing the DIN-rail footprint of the main device. The early-break function means this contact opens before the main poles close — wire the NC (normally closed) side into a safety or interlock circuit that must break before power reaches the load.
