MV network management - Easergy range
Amp 21D
Ammeter for MV switchgears
b At the leading edge of technology,
Amp 21D is suitable for Medium Voltage network
load management.
Easergy Amp 21D is an ammeter dedicated to display the load
current on a Medium Voltage network.
It is particularly suited for network load management application.
b Compact and in DIN format, it fits naturally
into MV cubicles.
PE57786
b Self-powered, it ensures a permanent display
of currents.
b Cost efficient, it uses the CT optimised
for Fault Passage Indicator.
b Performant, it displays phase current
and maximum of current.
Functions
