METERING Mode is available on all trip unit types (Mpro S &
Mpro N ) and can be used to access and to indicate the electrical
parameters of the circuit in which the circuit breaker is
installed..
The Mpro S Trip Units are always supplied with an Ammeter
that measures and indicates the current in the L1, L2 & L3
phases and the neutral.
The Mpro N Trip Units is supplied with a unit that measures the
parameters and units as indicated in table 2.12. To access all
voltage related parameters the Trip Unit must be supplied with
voltage signals by using external single pole poten
Ɵ
al
transformers. These must be selected and connected In
accordance with the characteris

cs of the power supply (Wye
orDelta). For a power supply with a Wye construc
