Sensor for short-circuit

Type LK

This sensor is used for short-circuit detection. The potential-free connection between the sensor and the display unit is done by a fibre optic cable. The short-circuit sensor can be assembled on screened and unscreened cables. The sensor is mounted on the conductor or cable with a divisible stainless steel bracket. Therefore the sensor can be retrofitted.

The trip current can be selected by a 7-step rotary switch.
