Short circuit signaling contact APD/GV2 AK-1NZ EKF apd-am11

Additional accessory for motor starter (protector). A special contact that triggers only during an emergency shutdown of the motor starter due to overload. It has its own reset button and a trip indicator (flag). In normal state and during regular switching on/off with buttons, its contacts do not change. When the thermal release trips the motor starter due to overload, the emergency contact mechanism triggers: NO contact closes, and NC opens. At the same time, the flag switches, visually indicating a fault. This contact is used exclusively for "FAULT" or "OVERLOAD" signaling. It sends a signal to an alarm lamp, siren, or controller that the motor has shut down due to protection tripping rather than a command. Installed on the side (left) of the motor starter. Used for APD-32 and GV2P.
