PRODUCT INFORMATION
Sensor for earth-fault
Type LE
This sensor is used for earth-fault detection. The potential-free connection between the sensor and the display unit is done by a fi bre optic cable. The sensor must be mounted on screened cables.
A divisible layered steel ring is laid around all three phases to measure the sum current and it can be retrofitted. The sensor is fixed with a cable tie on the conductor or cable.
