Intriguing Introduction
The intelligently designed DAM3-1600 molded case circuit breaker is programmed to autonomously disconnect the current upon surpassing the preset release threshold. The 'molded case' refers to the robust plastic insulator that forms the device's frame, ensuring complete insulation of the conductor and the metallic grounding component, epitomizing safety and reliability.
Innovative Working Principle
The operation of the DAM3-1600 molded case circuit breaker is characterized by either manual manipulation or electric closure of the main contact. Once closed, the free-release mechanism diligently secures the main contact in place. This sophisticated device integrates the overcurrent trip coil and thermal trip element in series within the main circuit, while the undervoltage trip coil operates in parallel with the power supply, offering an exquisite balance of control and protection.
