Overview of DAM3-100 MCCB molded case circuit breaker
The rated insulation voltage of the Dada DAM3-100 molded case circuit breaker can reach up to 100V. These electrical devices are suitable for power distribution circuits with an alternating current of 50-60Hz, a rated operating voltage up to 750V, and rated operating current from 10A to 100A. The circuit breaker plays a vital role in distributing power and protecting the circuit and power equipment from overloading, short circuits, and undervoltage failure damage. They can also be used in electric motors for infrequent starting and overload protection as well as protection against short circuiting and undervoltage conditions.

Compared with the DAM1 series, the DAM3 series are designed for smaller volume, higher breaking capacity, offering additional energy savings.

Introduction
The DAM3-100molded case circuit breaker automatically cuts off the current when the current exceeds the release setting. The molded case refers to the plastic insulator used as the frame of the device to insulate the conductor and the metal grounding component.

Working principle
The main contact of DAM3-100 molded case circuit breaker is manual manipulation or electric closing. After the main contact is closed, the free release mechanism locks the main contact into the closing position. The overcurrent trip coil and the thermal trip element are connected in series with the main circuit. The undervoltage trip coil and the power supply are connected in parallel.
