Product Description

DAM3-1600 MCCB Molded Case Circuit Breaker

Overview
The Dada DAM3-1600 molded case circuit breaker boasts a rated current reaching up to 1600A, making it an ideal choice for safeguarding power distribution circuits with an alternating current of 50-60Hz and a rated operating current up to 1000A. These versatile electrical devices also provide reliable protection for electric motors, shielding them from overload, short-circuiting, and undervoltage conditions, while allowing for infrequent starting.

The DAM3 series stands out from the DAM1 series with its more compact design, higher breaking capacity, and improved energy efficiency, making it an advanced solution for modern electrical needs.

Introduction
The DAM3-1600 molded case circuit breaker is engineered to automatically interrupt the current flow when it surpasses the preset release setting. The 'molded case' aspect refers to the robust plastic insulator frame that effectively insulates the internal conductor and the metal grounding components, ensuring safety and reliability.

Working principle
The main contact of the DAM3-1600 molded case circuit breaker can be operated manually or via electric closing. Once the main contact is closed, the free release mechanism securely locks it in place. The overcurrent trip coil and thermal trip element are connected in series with the main circuit, while the undervoltage trip coil is connected in parallel with the power supply, ensuring comprehensive protection and operational efficiency.
