Introduction
The DAM3-1600 molded case circuit breaker is engineered to deliver automatic current interruption when the current surpasses the preset release threshold. Its design features a durable plastic insulator as the framework, effectively insulating the conductor and metal grounding components to ensure safety and reliability.
Working principle
The DAM3-1600 molded case circuit breaker operates with precision, featuring a main contact that is either manually operated or electrically closed. Once closed, the free release mechanism securely locks the main contact in position. The overcurrent trip coil and thermal trip element ingeniously integrate in series with the main circuit, while the undervoltage trip coil operates in parallel with the power supply, ensuring seamless and reliable performance.
