Residual current circuit breaker RH99P with manual reset 0.03-30A 56272

Residual Current Device – Protection and Safety of Installations

The RH99P residual current device is a reliable device used to protect electrical circuits from the effects of leakage currents and short circuits to earth. Its design with manual reset provides additional safety, requiring physical intervention to restart after activation, minimizing the risk of unintentional reconnection in the event of a permanent fault. The device is designed to operate in alternating current circuits and finds application in both domestic and industrial installations.

Functionality and operating parameters

The RH99P is characterized by a wide setting range of the differential current, from 0.03 to 30 mA, allowing for precise adjustment to the specifics of the protected installation. The rated operating frequency is from 50 to 400 Hz, ensuring compatibility with various power systems. The device is powered by AC voltage with a value of 110-130 V. It is worth noting the maximum permissible time delay when power is applied, amounting to 4.82 s – a parameter important for ensuring a quick response in the event of a failure. Equipped with a clamp terminal, it facilitates mounting and connection of wires.
