Integrated measurement on electronic DPX³

The new electronic DPX³ 250, 630 and 1600 MCCBs with integrated measurement functions provide access to the parameters of the installation in a compact unit.

The values measured can be viewed:

- Directly on the electrical panel, on the LCD on the front of the device

- Remotely from a PC or smartphone equipped with supervision software, via the RS485 communication interface and the Modbus protocol


The same depth from 16 to 250 A
