  "textContent": "A direct current residual current protection device having a controlled current discharge having a positive and a negative input terminal, a positive and a negative output terminal, a first switch, a controller and a discharge control circuit. The first switch is interposed between the positive input terminal and the positive output terminal and operatively opens/closes an electrical connection between the positive input terminal and the positive output terminal. The controller has a current imbalance detection for a detection of a current imbalance between the positive and the negative output terminal. When the current imbalance is detected, the controller opens the first switch. The discharge control circuit is connected on one end between the first switch and the output terminal and on second end to both negative input and negative output terminal. The discharge circuit has a source of electrical energy that accumulates energy when the first switch is closed and discharges the accumulated energy when the first switch is opened.",
