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.
Ambient and installation conditions

Engineered to operate at altitudes up to 2000 meters,
Designed to function optimally within ambient temperatures ranging from -5ºC to +40ºC (up to +45ºC for marine applications);
Capable of withstanding the effects of damp environments;
Resistant to the impact of moulds;
Engineered to endure the effects of nuclear radiation;
Capable of operating reliably at a maximum inclination of 22.5ºC.
Ensuring reliable performance even when subjected to the normal vibrations of a ship;
Maintaining reliable functionality even during earthquakes with a magnitude of up to 4g.
Suitable for environments free from explosion hazards and isolated from corrosive gases or conductive dust that can damage metal or insulation integrity;
Protected from rain or snow exposure.
