It is a leakage current relay that identifies leakage currents in an electrical installation and protects people's life and property safety. In fact, if there is a fuse system in the electrical installation, it would confuse people who do not have enough knowledge about why a leakage current relay is needed. Once a leakage current relay is detected in an electrical installation, it detects the leakage current that damages both the people and the electrical system itself, the circuit elements and the electrical and electronic devices connected to the circuit in a very short time and cuts the passage of the electric current by opening the circuit. This prevents potential hazards.

The residual current relay is based on the phase and neutral balance in the installation. Under normal conditions, this balance should be equal. However, if there is a difference between the current flowing from the phase and the current leaving the neutral, if the currents are not equal to each other, there is an electrical leakage or short circuit somewhere in the system. In this case, the leakage current relay is activated.

Although the electrical fuse has a similar function, the current values ​​to be maintained by a fuse are higher than the leakage current relay. Current can pass through the human body like other conductors. It can resist up to 50 volts in dry conditions and up to 25 volts in humid environments. Even the milliampere current flowing through the human body can create dangerous consequences for health. In general, the human body can withstand up to 30 mA. However, fuses are usually 10, 16 or 32 amps and do not blow before. This value is extremely risky for human life. A residual current relay is only activated if the difference between 30 mA is on and off. It provides more reliable protection in this respect. In addition, the residual current relay switches on immediately if there is a possible leakage current in the installation and creates a fire hazard and prevents the risk of fire. In practice, the 300 mA residual current relay is used for protection against fire.

Our company, within the framework of electrical safety examinations, leakage relay measurements in accordance with the relevant regulations, standards and test methods published by domestic and foreign organizations. The standards considered in these studies include:
