3 - Ekip Measuring modules

Description The Ekip Measuring is an accessory module for measurement of voltage, power and energy.
Compatibility and power supply The Ekip Touch trip unit can be equipped with the Ekip Measuring and the Ekip Measuring Pro modules, the

Specifically:
• It measures the r.m.s. value and frequency of the voltages of the three-phase system on the internal
contacts of the circuit-breaker, or on the external sockets. From these measurements, the trip unit obtains
the power and energy ones, which therefore become available.
• Combined with the Ekip Synchrocheck module, Ekip Measuring makes it possible to recognise whether
the synchronism conditions exist between the internal contacts (or external sockets) and external contacts
necessary for closing the circuit-breaker.
Two types are available:
• Ekip Measuring, equipped with the measuring function only.
• Ekip Measuring Pro, with a measuring function, possibility of powering the trip unit, and activation of the
Measuring protections.
With the Ekip Measuring Pro module, the power supply of the trip unit is guaranteed, if at least one value of
the line-to-line voltages is greater than or equal to 80 V AC.
former if you only wish to implement the measurement function and the latter if you also wish to implement
the power supply function and activate the Measuring protections. With Ekip Hi-Touch, G Touch, and G Hi-
Touch trip units, Ekip Measuring Pro is provided as standard.
Ekip Measuring requires the trip unit to be also supplied with auxiliary voltage (example: provided by an Ekip
Supply module). Auxiliary supply is not necessary with Ekip Measuring Pro.
