NDBU Series (Molded Case Circuit Breakers / Thermal-Magnetic Protection)
Product Description
The ABB NDBU-95C (64008366D / 3AFE64008366) is a high-performance molded case circuit breaker (MCCB) designed for low-voltage power distribution systems. It provides reliable protection against overloads, short circuits, and fault currents while maintaining safety for both equipment and personnel.
This breaker is ideal for industrial and commercial installations where medium to high power circuits need secure protection. It features thermal-magnetic tripping with adjustable current settings to provide precise protection for a wide range of applications. The modular design allows integration into switchboards, control panels, and motor distribution centers.
The NDBU-95C is built for durability, long-term operation, and minimal maintenance. Its robust construction and clear visual status indicators make it suitable for both frequent operational and emergency conditions.
