Additional front contact block APD/GV2 DKP-11 NO+NC EKF apd-ae-11

Additional accessory for the motor starter (protection). Front contact block. It contains one pair of normally open (NO) and one pair of normally closed (NC) contacts. The NO contact closes only when the starter is manually activated (by a button or control signal). Used to provide a "Motor running" signal (e.g., to an "ON" lamp on the panel). The NC contact opens when the starter is activated. Used for "Motor stopped" signaling or in interlocking circuits (e.g., to prevent the simultaneous starting of two motors). This block DOES NOT OPERATE during an emergency shutdown by protection. Installed on the front of the starter. Used for APD-32 and GV2P.
