Ableitstromschutzrelais

We're offering various models of high-quality earth leakage relays.

Our products are intended for various applications. We have extensive experience in sales, thus we can help you and support you in choosing the right solution.

The X...DB3 series earth leakage relays Type B 

Designed to measure the DC, AC, and high-frequency leakage current. Thanks to their distinctive feature (the displaying of the leakage current) it is possible to continuously monitor the insulation state and to program the preventive maintenance in order to avoid unexpected power brakes.

The X48DSA series earth leakage relays 

Designed to measure the leakage or unbalance currents caused by conductors or appliances insulation losses and to react, in case the set limits are exceeded, switching off the power supply to the defective system.

Main features and functions:

• Wide range of trip currents and delays to guarantee the necessary selectivity in order to keep in operation the parts of the system not involved in the fault.
• Three ranges of tripping current and delay to increase the setting accuracy.
• Continuous check of the good connection with the toroidal transformer, performed on the measuring winding, with trip action in case of negative result.
• Selectable manual or automatic reset.
• Inputs for remote reset.
