If the circuit breaker does not trip, or the earth-leakage indicator does not change to yellow, check that the circuit breaker is energized. If the circuit breaker is energized correctly, and has not tripped or indicated the earth-leakage fault, replace the MicroLogic4 trip unit. The first reason is that the design configuration is different The design principle of the distribution system is to realize the step-by-step protection from the standard distribution. The leakage protection device works on the basis of leakage current detection, which is an effective safeguard measure for electric power at present. Therefore, it is of great significance to find the leakage position quickly and accurately, and deal with it in time.

Frame rated current of leakage release is 63A, can be connected to the wire of 10mm² and 25mm². The leakage protection switch is suitable for the circuits of AC 50Hz, rated voltage of 230V ~ 400V, rated current of 63A, mainly consists of the zero-sequence current transformer, electronic components board, leakage circuit breakers. Leakage current refers to the unintentional flow of electric current between an energized conductor and any other conducting surface or material. Sigma Illegal Current Protection switches save lives, protects from fire Illegal current protection switches are protective electrical equipment that should be used against electric leaks that risk life and property safety.

Waterproof distribution box manufacturers tell you that the way to waterproof an outdoor distribution box is to first choose a distribution box made of waterproof material, seal the cable entry points, apply silicone sealant, install a weatherproof cover, use. Imagine opening an electrical distribution box only to find water droplets clinging to your expensive components like dew on morning grass. Key design points include high-quality materials like ABS plastic, aluminum, and stainless steel that resist corrosion and UV. Away from moisture and corrosive environment The installation location should be away from moisture sources and corrosive environments. The box should be installed in a dry and well-ventilated place to avoid aging of insulation materials or electrical short circuits that may be caused by moisture.
