Nader NDM5E series MCCB is applicable to the power grid circuit with AC 50Hz / 60Hz, rated working voltage AC380V to AC690V, and rated working current 32A to 1600A. The product can be used for infrequent conversion in the circuit, and has the functions of long delay, short-circuit short delay, instantaneous, grounding, pre alarm and undervoltage protection (with undervoltage release). It can protect the line and power supply equipment from damage. It can also feed back the current, voltage, power, electric energy, frequency, service life, opening and closing status, operation times and other information of the product to the upper computer or other energy efficiency management system, which is used to detect and monitor the circuit breaker, reduce the operation and maintenance cost of the power network, and provide necessary data for the future energy efficiency system This product has the characteristics of small volume, high breaking capacity, short arcing and anti - vibration
Nader NDM3E-250 / 400 / 630 IOT MCCB is suitable for power distribution protection with AC 50Hz / 60Hz, rated working current 63A to 630A, rated insulation voltage 1000V and rated working voltage AC380V / 400V / 415V The circuit breaker has the functions of long-time delay, short-circuit short-time delay, instantaneous, over-voltage and under voltage and phase failure protection, and plays a protective role for the line and power supply equipment. It has the ability to feed back the current, voltage, power, electric energy, life and other information of the products to the terminal equipment, and the accuracy reaches the level of the electric meter. It is used to detect and monitor the load end, reduce the operation and maintenance cost of the power grid, and provide necessary data for the future energy efficiency system The product complies with IEC60947-2 and GB / GB/T14048.2 standards
Nader NDM3L series MCCB is mainly used in circuits with AC 50Hz / 60Hz, rated working voltage of 380V to 415V and rated working current of 16A to 800A for infrequent conversion and infrequent starting of motors. The circuit breaker has the functions of overload, short circuit and undervoltage protection, which can protect the line and power supply equipment from damage. At the same time, it can also provide protection against fire hazard and personal electric shock caused by long-term grounding fault that cannot be detected by overcurrent protection
