About this item

• Residual Current Adjuatable: 30mA-500mA
• Tripping Time Adjustable: 0.1s-0.5s(time delay ELCB)
• Distribute Electric Energy – Mainly used to distribute electric energy and protect circuits and power equipment from overload, short circuit, earth leakage, under voltage and other faults
• Good Flame Retardancy – The thermosetting material has good flame retardancy, will only gradually carbonize even if encounters an open flame, and will not burn, so that is safe
• Suitable For Extreme Environments – Rated current for 250A, frequency is 50/60Hz. Environmental operating temperature from 20℃60℃, suitable for more extreme environments
• Short Circuit And Overload Protection – Possess the characteristics of small size, short circuit protection, overload protection, flame retardant shell, high segmentation, short arcing, etc.
• Protection Of Motor – Can also be used for infrequent starting and overload, short circuit and under voltage protection of the motor
