Robust short-circuit sensor for medium-voltage networks

The LK short-circuit sensor is used for reliable detection of short-circuit currents in medium-voltage networks. Signal transmission to the display device is potential-free via an optical fiber cable, ensuring safe separation between the sensor and the display. The sensor can be installed on shielded and unshielded conductors. Thanks to the separable stainless steel bracket, easy retrofitting is also possible in existing systems. The response value is set directly on the sensor using a rotary switch.

• Potential-free connection to the display device via optical fiber
• Can be mounted on shielded and unshielded conductors
• Seven selectable response values from 200 A to 1200 A
• Split stainless steel bracket for easy retrofitting
• Fully encapsulated design with IP67 protection rating
