Additional Information
Working Principle: The main contact of the MCCB is controlled either manually or electrically. Once closed, a locking mechanism secures the contact. The overcurrent trip coil and thermal trip element operate in series with the main circuit, while the undervoltage release coil is connected in parallel with the power supply.
The DAM1 MCCB offers flexible connection methods, which can be made using cables, extended busbars, spreader terminals, or cable lugs.
