Presentation Two Measurement modules are available:
Measurement performance The measurement performance provided when the Measurments modules are installed (described on page
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 11.
Isolation transformer The isolation transformer must conform to standard IEC 60255-27 and possess the following characteristics:
Parameters The specific configuration area will activate in the Settings - Modules - Ekip Measuring menu if the Measurement
Replacement The Measurement module can be replaced on its Trip unit, for details consult document 1SDH001330R1002.

• 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 description
of module in manual 1SDH001330R1002).
39), are more accurate when the Class 1 Power & Energy Metering package is present (described on page 41).
• 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 1150 VAC line-to-line voltage can be connected and configured in the presence of
connections to external sockets and an isolation transformer.
Characteristics Description
• Accuracy class: ≤ 0,2
• Performance: ≥ 10 VA
• Overload: 20 % permanent
• Insulations: 4 kV between inputs and outputs, 4 kV between shield and outputs, 4
Electrical
kV between shield and inputs
• Frequency: Fn +-10%
• Primary voltage: 100 to 1150 V (nominal, to be configured via menu)
• Secondary voltage: 100 to 230 V (nominal, to be configured via menu)
module is detected correctly by the trip unit.
The rated voltage, the presence and relative parameters of the isolation transformer, the power flow and
presence of external neutral voltage (with 3P circuit-breaker) can be configured in this menu.
WARNING! if the Class 1 Power & Energy Metering package is present, module
replacement will impair the performance values indicated on page 41; consult ABB
to assess solutions able to comply with your requirements
