Product Description

Product Description

RM6 is a gas-insulated switchboard combining all medium voltage functions to enable the connection, supply and protection of transformers for open ring or radial networks.

Transformer protection can be achieved either:

• By a fuse-switch combination for transformers up to 2 000 kVA

• By a circuit breaker with a protection relay for transformers up to 8 000 kVA

In addition to HV/MV substations, which are used to limit the effects of a fault on the network, operating a distribution network sometimes requires several switching

points. RM6 offers solutions for up to five network connections thanks to:

• Line protection with 630A circuit breakers

• Network switching by switch disconnectors

• Integrated power supply remote control devices.
