Introduction
The DAM1-1600 molded case circuit breaker is designed and distributed by Dada to distribute electrical energy, start asynchronous motors at infrequent intervals, protect power lines and motors, and automatically cut off the circuit in the case of serious overload, short circuit, and under voltage fault conditions. The molded case circuit breaker operates in an equivalent manner to combination fuse-switches and thermal relays.

Application
DAM1-1600 molded case circuit breakers are low-voltage circuit breakers. They meet the installation needs of small users all the way to large industrial substations and power distribution systems. They are commonly applied in steel mills, oil platforms, hospitals, railway systems, airports, computing centers, office buildings, convention centers, theaters, skyscrapers, and other large scale structures.

Optional accessories of DAM1-1600 molded case circuit breaker
Undervoltage trip, shunt trip, auxiliary contact, alarm contact, auxiliary alarm contact, manual manipulation, electric operation, flashboard, clapboard, lengthening handle.

Working principle
The main contact of DAM1-1600 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.
