Presentation Two Measurement modules are available:
Measurement performance The measurement performance provided when the Measurement modules are installed (described on
Configurations available Both modules can be ordered with different connection configurations:
Electrical characteristics The Measurement modules function correctly in the electrical conditions described on page 20.
Isolation transformer The isolation transformer must conform to standard IEC 60255-27 and possess the following

• Measurement enabler installed by default on Ekip Touch and enabled in the presence of the
Measuring Measurements package (enabling can be obtained both at the time the circuit-breaker
is ordered or at a later date, via Market Place)
• Measurement enabler with voltage socket is installed by default on Ekip Hi-Touch, Ekip G Touch
and Ekip G Hi-Touch; can be installed in conjunction with Ekip Touch if requested when circuit-
breaker is ordered
Both modules measure voltages, frequencies, power and energy values; in addition, the Measurement
enabler with voltage socket module allows:
• the Trip unit to be supplied directly by the voltage sockets to which it is connected
• management of the synchronism function when the Ekip Synchrocheck module is installed (see
chapter dedicated to Ekip Synchrocheck from page 247).
page 117), are more accurate when the Class 1 Power & Energy Metering package is present (described on
page 120.
• connections to internal terminals or in an external terminal box
• connections to the upper or lower terminals of the poles on the basis of the expected power flow
• with normal or reverse pole order
For full details about ordering and the connections, consult technical catalog
wiring diagrams 1SDM000091r0001.
Installations with up to 1200 VAC line-to-line voltage can be connected and configured in the presence of
connections to external sockets and an isolation transformer.
