DLT

The voltage-limiting device is a single-phase device. It is designed to be inserted into the earth connection for measurements with a circuit-breaker tester, for example. The voltage-limiting device has two positions.
In “OPEN” position (measurement position)

- Protects users against accidental voltage recurrence by re-establishing the grounding circuit.
- It limits the voltage at its terminals to less than 50 Volts.

In the “CLOSED” position, it restores the earthing circuit.
