MODELS WITH COVER AND INSTALLED MINIATURE CIRCUIT BREAKER
EWRC 500 NT BREAKER | EWRC 500 NT 4-DIN
The versions with front door allow direct access to the switch miniature circuit breaker or to the top of the device
installed on the DIN rail mounted inside.
To open the front door, use both hands as shown above. Apply a slight pressure with your thumbs on top to
release the side flaps. Simultaneously with the index finger gently pull the door toward you.
In versions provided with the miniature circuit breaker, the installer must connect it to the power supply of the
electronic board through the wiring harness included in the packaging.
The wiring diagram is shown in the figure below.
In versions with transparent front door, the omega DIN rail is always available and already installed.
You can mount up to a maximum of 4 DIN modules, including 2DIN miniature circuit breaker when present.
The DIN housing is easily expandable from 2 to 4 DIN exploiting the pre-drilling barriers as shown in the top right.
