Product Description

DAM11 Series Moulded-case Circuit Breaker

Product overview

The DAM11, DAM11LY, DAM11RT, DAM11E, and DAM11EL series circuit breakers are our latest innovations, meticulously developed by Shanghai DaDa Electric Co., Ltd. These circuit breakers seamlessly combine the best features of leading international designs with the specific demands of both domestic and global markets.
Engineered with insulation voltage reaching up to 1000V, these circuit breakers are ideal for AC50Hz distribution systems, offering a rated working voltage of 690V and a rated working current range of 10A to 800A. They are essential for distributing electric power, safeguarding circuits and equipment from overload, short circuits, under voltage, and more. Additionally, they provide reliable protection for motors during infrequent startups, shielding them from overloads, short circuits, and under voltage scenarios.
Characterized by their compact size, high breaking capacity, and short flashover, these circuit breakers are the perfect choice for discerning users. They offer versatile installation options, whether vertically or horizontally, catering to diverse application needs.
Our DAM11DC series DC moulded-case circuit breakers are designed for DC systems with a rated voltage up to and including DC 1000V and a rated current range of 10A to 800A. These breakers effectively distribute electric power and protect circuits and equipment from overloads, short circuits, and more.
These products feature flexible wiring options, allowing connections from both the top and bottom, and are designed to be polarity-free for added convenience.
They adhere strictly to international standards, including IEC60947-2 and GB14048.2, ensuring top-notch reliability and safety.
