Nader Circuit Breaker

Features of NDM3DE Series

According to the rated ultimate short-circuit breaking capacity, the circuit breaker is classified into four types: S, M, H, and U. It breaks through the structural and dimensional limitations of existing IoT circuit breakers, featuring compact size and high breaking capacity.
It can feed back product information such as current, voltage, power, electrical energy, and service life to terminal devices, with meter-level accuracy. It is used for load-side detection and monitoring, reducing power grid operation and maintenance costs and providing necessary data for future energy efficiency systems.
