Makel Three Phase 4X40A 300Ma 3Ka Residual Current Relay Fire Protection

Makel Three Phase 4x40A 300mA Residual Current Relay Fire Protection

Turkey's brand Makel 100% Domestic Production Produced in Istanbul Kıraç Makel Factories.

In order to protect human life, residual current circuit breaker with 30 mA sensitivity and 300mA sensitivity for fire protection should be used. In the system where residual current circuit breakers are used, the neutral line must be isolated and must not be grounded between the switch and the load. Since the residual current circuit breakers do not protect against short circuit, overcurrent, thermal-magnetic current, automatic fuses etc. must be used in the installed system against short circuit and overload currents. device(s). The nominal current of the residual current protection switch must not be less than the current flowing through the circuit it is connected to. The neutral line must be passed through the residual current protection switch together with the phase and phases. Attention should be paid to the input and output directions. Very long cables should not be used after the residual current circuit breaker, especially after devices with a life protection threshold of 30mA. Capacitive leakages and insulation faults of the cables should not be ignored. 2-pole residual current protection switch should be used in single-phase networks and 4-pole in three-phase networks.
