Introduction
The DAM3-1600 molded case circuit breaker is engineered to automatically interrupt the current when it surpasses the preset release threshold. Featuring a durable plastic insulator as its frame, it effectively isolates the conductor from the metal grounding components, ensuring optimal safety and performance.

Working Principle
The DAM3-1600's main contact can be engaged manually or electrically. Once closed, the device's free release mechanism securely locks the main contact. The overcurrent trip coil and thermal trip elements are wired in series with the main circuit, while the undervoltage trip coil is connected in parallel with the power supply, facilitating precise and dependable protection.
