Section: Overview
The robust and highly efficient Dada DAM3-1600 molded case circuit breaker is engineered to handle a substantial rated current up to 1600A. These cutting-edge electrical devices are indispensable for safeguarding power distribution circuits with alternating current ranges of 50-60Hz, and adeptly manage a rated operational current up to 1000A. Not only are they perfect for the infrequent starting of electric motors, but they also provide exceptional protection against overloads, short circuits, and undervoltage conditions, ensuring superior performance and reliability.
The innovative DAM3 series outshines the DAM1 series by boasting a more compact design and significantly higher breaking capacities. This translates into remarkable energy efficiency and savings, making it the ideal choice for modern electrical applications.

Section: Introduction
The state-of-the-art DAM3-1600 molded case circuit breaker is designed to automatically interrupt current flow as soon as it surpasses the predefined release setting. The term 'molded case' pertains to the durable plastic insulator that serves as the framework of the device, ensuring safe insulation of the conductor and the metal grounding component, thus providing unparalleled safety and reliability.
Section: Working Principle
The DAM3-1600 molded case circuit breaker's main contact can be maneuvered either manually or by electric actuation. Once closed, the ingenious free release mechanism ensures the main contact remains securely locked in its closed position. Remarkably, the overcurrent trip coil and the thermal trip element are ingeniously connected in series with the main circuit, while the undervoltage trip coil is paired in parallel with the power supply, showcasing a sophisticated design that guarantees optimal performance.
