The GS1AM3 is an auxiliary early-break and signalling contact from the TeSys GS range, designed for switch-disconnectors rated 630 to 1250 A. It provides three changeover (C/O) contacts that open ahead of the main poles, giving a clean status signal before the load circuit breaks — useful for PLC handshake or safety interlock chains where you need to confirm the disconnect is opening before downstream contactors drop out.
Rated operational current — what the numbers mean
The contact ratings span multiple duty classes, so the right one depends on your load type. At 24 V DC-13 (solenoid/electromagnetic load) it carries 12 A. For AC-15 (inductive loads like contactor coils) it handles 4 A at 230 V and 3 A at 400/415 V. At 48 V DC-13 it's rated 2 A, dropping to 0.6 A at 110 V DC-13 and 0.4 A at 220 V DC-13. The 2 A at 440 V AC-15 covers higher-voltage control circuits. Match your circuit voltage and load category to these figures — a 24 V DC solenoid bank at 10 A is fine, but the same bank at 110 V DC needs to stay under 0.6 A per contact.
