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.

Configuration

Connecting busbars Phase separators Set of screws for panel mounting Set for connecting external conductors

Auxiliary devices for DAM1 MCCB

1 - Power circuit breaker 

2 - Mounting panel (base) for plug-in/draw-out) option 

3 - Side panels for draw-out option 

4 – Phase separators 

5 – Connecting busbars 

6 – Plug-in contacts 

7 – Blocking unit

8 – Terminal cover 

9 – Casing cover
