Introduction
The DAM3-1600 Molded Case Circuit Breaker is a marvel of safety technology, designed to automatically cut off the current when it exceeds preset limits. Its molded case, made from high-quality plastic insulators, ensures effective isolation of the conductor and grounding components, providing unparalleled reliability and security.
Working Principle
The operation of the DAM3-1600 Molded Case Circuit Breaker is a blend of manual manipulation and electric closing. Once the main contact is closed, the free release mechanism securely locks it into position. With the overcurrent trip coil and thermal trip element in series with the main circuit, and the undervoltage trip coil in parallel with the power supply, this MCCB is engineered to deliver optimal performance and safety.
