DAM1 series electronic type Moulded case circuit breaker(MCCB)
3P 400V/415V electronic type Moulded case circuit breaker high quality
Introduction
Circuit Breakers with Electronic Over Current Release:
The feature discriminating electronic circuit breakers from thermal-magnetic
breakers is to control the over current releases with electronic is circuit. Electronic is
control is performed via microprocessor.During design of the electronic circuit,
worst possibilities to encounter in operation have been taken into consideration. In high circuit currents, direct opening has been ensured without operating electronic circuit. In this way, possibility of failure in the electronic circuit has been eliminated.
-Maximum, minimum, average etc. Values of the drawn current at various time intervals (day-night) can be takenRated and Instant opening current adjustment areas of electronic circuit breakers are quite wide. This feature allows wide use opportunity to the breaker Furthermore, electronic circuit breakers are not affected from ambient temperatures.

Working principle
The main contact of the 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 over current trip coil and the thermal trip element are connected in series with the main circuit. The under voltage release coil and the power supply are connected in parallel.
