Residual current device RH99P7 110/130VAC 0.03-30A 56506

Residual Current Device – Protection and Control of Circuits

The RH99P7 residual current device is a reliable device designed to protect electrical installations from the effects of leakage currents and short circuits. Designed to work with alternating current circuits, it provides a quick and effective response in the event of a fault, minimizing the risk of damage and fire. It is a key element in protection systems, both in professional and domestic applications.

Functionality and Application

The RH99P7 device finds application in a wide range of electrical installations, including residential, commercial and industrial buildings. Thanks to the adjustable current setting range (0.03 – 30 mA), it can be adapted to the specific requirements of a given circuit. This allows for precise protection against leakage currents, which may be caused by insulation damage or other irregularities. The use of a residual current device significantly increases the safety of using the electrical installation.

Characteristics and Construction

The device is characterized by a compact design with dimensions of 72 x 72 x 92 mm, which facilitates installation even in limited space. It has clamp terminals providing a secure and durable electrical connection. The device requires an external AC power source with a voltage of 110-130V at a frequency of 50-400 Hz. It is equipped with one normally open and one normally closed contact, allowing integration with various control and signaling systems. Thanks to the lack of a fault memory function, after removing the cause of the trip, the device automatically returns to the ready state. The rated switching current is 8A.

• Wide current setting range: from 0.03 mA to 30 mA allows for precise adjustment to the needs of a specific installation.
• Universal supply voltage: the ability to power from an AC network with a voltage of 110-130V (50/60 Hz) ensures installation flexibility.
• Compact dimensions: facilitate installation in tight switchboard spaces.
• Clamp terminals: guarantee quick and reliable connection of wires.
• For AC circuits: dedicated to working with alternating current, providing optimal protection against leakage currents.
• No differential current indicator: focus on the basic protection function without unnecessary visual additions.

The RH99P7 residual current device is a solid and reliable solution for anyone who cares about the safety of their electrical installation and the comfort of using electrical devices. Its versatility and ease of installation make it an ideal choice for both professionals and home users.
