Metering protection
Administration box: main panel protection
Houses the main breaker, the surge protection and the busbars with the same level of armoring as the metering box.
What it is for
Protect the main panel
Main breaker, surge protection and busbars in an armored 900 × 2,000 × 300 mm box.
Choose the level of control
It opens by Bluetooth or by coded screw, depending on the level of control each installation needs. The coded mechanical key remains as a contingency.
Know if the door is open
A sensor shows whether the door is open or closed, and the seismic alarm warns on forced opening.
Internal layout: upper compartment for the individual breakers, housing for the 100/400 A main breaker and a lower section for the busbars. The Bluetooth system is isolated by a dedicated breaker.

Access and installation
Bluetooth opening
Opening is ordered from the operator's phone, with individual access control and a record of every event. The coded mechanical key remains as a contingency.
Electrical interlock, optional
On a forced-opening attempt, the seismic system trips the breaker coil and cuts the power automatically. It is an optional function.
Anti-theft screw and single-line diagram
High-hardness steel key with a secret geometry that does not allow conventional tools; the secret can be regionalized per utility. The installation's single-line diagram is delivered according to the project.
