Nader NDB1-125 series MCB is mainly used for short-circuit protection, overload protection, control, isolation and DC system protection of terminal power distribution system with AC rated working voltage of 230V to 415V, DC rated working voltage of 60V to 80V, rated frequency of 50Hz, rated working current of 50A to 125A and pole number of 1p, 2P, 3P and 4P It is widely used in low voltage terminal power distribution in industry, civil buildings, energy, communications and infrastructure
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 NDP3 series modular terminal combination box is applicable to circuit terminals with AC 50Hz (or 60Hz), rated working voltage of 230V to 400V and rated current of 1A to 63A. It is usually not more than 35 ℃ and occasionally reaches 40 ℃. It is used to provide protection for circuit breakers, switches, sockets and other electrical accessories against external influences (such as mechanical impact, invasion of solid substances, etc.).
