Detailed Introduction
The DAM3-1600 molded case circuit breaker is a critical safety device, designed to automatically disconnect the current when it surpasses the preset release settings. Its 'molded case' signifies the robust plastic insulator forming the device's framework, ensuring secure insulation of the conductor and safeguarding the metal grounding components.
Intricate Working Principle
The operational brilliance of the DAM3-1600 molded case circuit breaker lies in its versatile manual or electric closing of the main contact. Once closed, the free release mechanism ensures the main contact remains firmly locked in position. The sophisticated design integrates the overcurrent trip coil and thermal trip element in series within the primary circuit, while the undervoltage trip coil is strategically connected in parallel with the power supply, epitomizing advanced electrical engineering.
