Zusammenfassung:	Device for detecting and locating breaks in conductors in a low-voltage electrical system with three phases and neutral. The device enables breaks in one or more conductors in a low-voltage electrical system with three phases and neutral to be rapidly visualised. It consists of a unit (1) on which there are three terminals for connecting phases (2) and one terminal for connecting the neutral (3). The presence of voltages on the phase lines is indicated by three green LEDs (4), a break in the neutral line or confirmation of a phase fault is represented by a red LED (5). Diodes (6) are used as protection against reverse voltages for the LEDs (4) and (5). Resistors (7) limit the current in the diodes connected to them.
