The GS1AX21 is a door interlock from the TeSys GS range, designed to prevent enclosure access while the switch-disconnector is in the ON position. It uses a Ronis EL11AP keylock type, meaning the key is trapped in the lock when the switch is closed, and can only be removed when the switch is in the OFF position — a standard safety interlock sequence for padlocking or group-locking schemes. This is an interlocking accessory, not a standalone switch. It mounts to the enclosure door and interfaces with the rotary handle of a TeSys GS switch-disconnector. If you're specifying a panel where the door must stay locked until the load is isolated, this is the part that enforces that sequence.
