DIRIS B-10L - 551174A - SOCOMEC
6.3.3. Connection to the electrical network and to the loads
The DIRISB-10L can be used on either single-phase, two-phase or three-phase networks.
Different loads will then be measured simultaneously, allowing great exibility in terms of where it is tted in the installation.
The loads are measured using several types of sensor (closed, split-core, exible) selected depending on the application. The
link between the DIRISB-10L and its associated sensors is performed using cables with RJ12 connectors. These connectors
enable rapid, trouble-free installation, in complete safety, with no risk of the connector being inverted, and also offers
automatic detection of the connected sensors.
In addition, the DIRISB-10L is able to identify the majority of load types to be measured: single-phase, three-phase with or
without neutral using 1, 2, 3 or 4 sensors for balanced or unbalanced loads. Several loads can be measured simultaneously.
The overall accuracy of the DIRIS B-10L + sensors measurement chain is guaranteed. To guarantee this accuracy,
SOCOMEC cables must be used for the current sensors.
6.3.3.1. Congurable loads based on the network type
The table below summarises the loads that it is possible to congure depending on the type of network at the installation.
Network type Configurable load
1P+N 1P+N – 1CT
2P 2P – 1CT
2P+N 2P+N – 2CT / 2P – 1CT / 1P+N – 1CT
3P* 3P – 3CT / 3P – 2CT / 3P – 1CT
3P+N 3P+N – 4CT / 3P+N – 3CT / 3P+N – 1CT / 3P – 3CT / 3P – 2CT / 3P – 1CT / 1P+N – 1CT
(*) Note: Single-phase loads cannot exist on a 3P network.
