1. Product overview
The Moulded Case Circuit Breaker (DAM1 Series) is a high-performance protection device designed for modern power distribution systems, suitable for AC 50/60Hz, rated voltage up to 690V, rated current up to 800A circuits. Its core functions include overload protection, short circuit protection, undervoltage protection and leakage protection (some models), which can be widely used in industrial power distribution, building power system, new energy power generation and other fields.

2. Technical highlights
High score breaking ability and safety guarantee：
CDC arc extinguishing technology is used to achieve zero or short arc design, which significantly reduces the harm of arc to equipment and personnel, especially suitable for enclosed power distribution cabinets with compact space.
The breaking capacity covers type C (economic) to type H (high score), and the maximum breaking current can reach 100kA to meet the protection needs of different scenarios.

Intelligent and modular design：
Support three-stage protection (overload long delay, short delay, short circuit instantaneous), through the electronic trip to achieve accurate current control, improve the reliability of the distribution system.
Modular accessories (such as shunt release, undervoltage release, alarm contacts) can be flexibly expanded to meet the needs of smart grid remote monitoring.

Environmental adaptability and certification standards：
Through the nuclear industry 1E test, ship condition test and seismic test (4g acceleration), suitable for offshore platforms, chemical parks and other harsh environments.
Comply with IEC 60947-2, GB/T 14048.2 and other international and national standards to ensure global market compatibility.

3. Application scenarios
Industrial power distribution: provides overload and short circuit protection for transformers, motors, and cables, and supports frequent start-stop scenarios.
New energy field: Adaptive photovoltaic inverter, wind power distribution cabinet, to ensure the stability of green energy system.
Intelligent building: combined with leakage protection functions (such as DAM1L series), used for ground fault protection in commercial complexes, hospitals and other places.
Marine and nuclear power: salt spray and corrosion resistant design meets special industry safety standards.

4. Industry trends and market value
With the acceleration of global energy transformation, power distribution equipment is developing in the direction of intelligence and high reliability. The DAM1 series has become the preferred alternative to traditional fuses and thermal relays due to its modular scalability, high breaking performance and multi-scenario adaptability. According to industry analysis, the global market size of plastic-case circuit breakers is expected to exceed $8 billion in 2024, of which the Asia-Pacific region occupies a leading share due to the growth of infrastructure demand.

5. Conclusion
The DAM1 series of moulded case circuit breakers redefines the standard of distribution protection through technological innovation and scenario-based design. In the future, with the deep integration of Internet of Things technology and renewable energy, this series of products will continue to promote the evolution of the power system to a safer and more efficient direction.
