A TYPE
Leakage current protection switches become activated in case of a leakage current in your connected mains and protects you and your environment from possible electric shock and fire dangers.
Makel Leakage Current Protection Switches are produced in accordance with TS EN 61008-1 standard, it comes with 3 kA,
6 kA and 10 kA short circuit cutting capacity, provided with 2 and 4 pole product choices, it presents easy mounting and safe
protection with 92 different product types.
Life protection leakage current protection switches;
Within international standards, a current level over 30mA passing through human body is the lethal threshold for life. Life protection leakage current protection switches cuts the current in case it exceed this level and provides a secure safety.
Leak Current Protection Switches With Fire Protection;
In the same time, 300mA leakage current is the threshold for the nominal cable installation materials to melt, burn or set flames. With the heat level achieved in 300mA current level, fire hazard becomes the issue. The leakage current protection with 300mA threshold value for fire protection cuts the energy of the current and provides secure protection.
1. A 30mA value current protection switch for human life protection and a 300mA value current protection switch for fire protection shall be used.
2. Fire protection leakage current protection switches shall be mounted to the terminal box and human life protection switch with appropriate current threshold shall be mounted to the counter colon circuit.
3. The neutral line of the system with leakage current protection shall be isolated and it shall not be earthed in between the switch and load.
4. Because the leakage current protection switches do not provide protection for short circuit or thermic-magnetic current, there shall be automatic fuses or similar device(s) for short circuits and overload.
5. Because a short circuit in the leakage current protection switch output may harm the application systems and products, it shall not be tried.
6. After connecting the leakage current protection switch to the installation, in order to test its performance, press “Test Button”.
7. In order to prevent the device from overheating, the nominal current value of the leakage current protection switch shall be bigger than the current value passing through the circuit.
8. The neutral line must pass through residual current circuit breakers with phase and phases.
9. The phase and neutral line shall pass through the protection switch.The capacitive leaks of the cable and isolation faults shall be also taken into account.
10. In single phase mains, a 2 pole and in 3 phase mains, 4 pole leak current protection switch shall be used.
