Overview
The Dada DAM3-1600 molded case circuit breaker boasts an impressive rated current capacity of up to 1600A. Engineered for excellence, these devices are ideal for safeguarding power distribution circuits operating at an alternating current frequency of 50-60Hz and a rated operating current up to 1000A. Additionally, they are adept at providing protection for electric motors, ensuring infrequent start capability, overload protection, and robust defense against short circuits and undervoltage situations.
Compared to the DAM1 series, the advanced DAM3 series distinguishes itself with a more compact design, heightened breaking capacity, and superior energy efficiency, making it a formidable choice for modern electrical systems.

Introduction
The DAM3-1600 molded case circuit breaker is designed to automatically disconnect the circuit when the current surpasses the preset threshold. The term 'molded case' refers to the durable plastic insulator that forms the device's housing, ensuring effective insulation of the conductor and grounding components.
Working Principle
The primary contact of the DAM3-1600 molded case circuit breaker can be operated either manually or electrically. Once closed, the free release mechanism securely locks the main contact in place. The overcurrent trip coil and the thermal trip element are serially connected with the main circuit, while the undervoltage trip coil is arranged in parallel with the power supply, ensuring comprehensive protection and reliable performance.
