Choice of functional units

A wide choice of RM6 functions

RM6 benefits from a wide choice of MV functions enabling:
• The connection, power supply and protection of transformers on a radial or

open-ring network via 200 A circuit breakers with an independent protection
chain, or via combined fuse-switches
• The protection of lines by a 630 A circuit breaker
• MV Metering of private MV/LV substations.

The RM6 functions are described in the table below.

PM107091 Scalability of RM6

To support the evolution of your distribution network, RM6 can be extended with
a range of functions making it a truly scalable system.
The addition of one or more functional units can be carried out by simply adding
modules that are connected to each other via the busbar using dedicated field
bushings.
There are different types of extensible RM6:
• Right-extensible (-RE type)
• Left-extensible (-LE type)
• Extensible on both sides (-DE type)
• Non-extensible (-NE type)
