Residual current device RH99P7 220/240VAC 0.03-30A 56507

Differential relay RH99P7 is a component dedicated to ensuring safety in electrical installations, protecting against the effects of leakage currents and short circuits to ground. The device is designed to operate in alternating current circuits with a voltage of 220-240V and offers a setting range for the differential current from 0.03 to 30A.

Functionality and application

This relay is used to protect electrical circuits in residential, commercial and industrial buildings. Its main task is to detect irregularities in the flow of current, which may indicate damage to insulation or direct contact with a live wire. A quick response to such situations minimizes the risk of electric shock and prevents fires caused by short circuits. Thanks to the wide frequency range (50-400 Hz), the relay is universal and can be used in various types of installations.

Characteristics and construction

The device is characterized by compact dimensions – 72 mm width, 72 mm height and 92 mm depth – which makes installation easier even in limited space. It is equipped with clamp terminals, providing secure and quick connection of wires. The relay has one normally open contact and one normally closed contact, which allows its integration with various control and signaling systems. The lack of a fault memory function means that after removing the cause of the trip, the relay automatically returns to the ready state. The device requires an external power source with a voltage of 220-240V AC.
