Makel Three Phase 4x40A 30mA 3KA Residual Current Relay Life Protection

Makel Three Phase 4x40A 30mA Residual Current Relay Life Protection

Turkey's brand Makel is 100% Domestic Production, produced in Istanbul Kıraç Makel Factories.

A leakage current protection switch with a sensitivity of 30 mA should be used to protect human life, and a sensitivity value of 300 mA for fire protection. A fire-protected leakage current protection switch should be used for cabinets, and leakage current protection switches with a life protection threshold and amperage values of sufficient size should be used for meter-column circuits. In the system where residual current protection switches are used, the neutral line must be isolated and must not be grounded between the switch and the load. Since residual current protection switches do not protect against short circuit, overcurrent, thermal-magnetic current, the installed system must have an automatic fuse, etc. against short circuit and overload currents. device(s). Applications such as short-circuiting the residual current protection switch outputs should never be tried as they may damage the system and the product. After connecting the residual current protection switch to the installation, press the "Test Button" to test the operation of the device. In order to prevent damage to the device due to overheating The nominal current of the leakage current protection switch must not be less than the current passing through the circuit to which it is connected. The phase and neutral line together with the phases must be passed through the leakage current protection switch. Input and output directions should be taken into consideration. Very long cables should not be used after the residual current protection switch, especially for devices with 30mA life protection threshold. Capacitive leaks and insulation faults of the cables should not be ignored. A 2-pole leakage current protection switch should be used in single-phase networks and a 4-pole leakage current protection switch should be used in three-phase networks.
