do not confuse System 50 switchboards with off the shelf 'meccano like' frame systems

Wall Mounted Switchboards

Wall mounted switchbaordA derivative of the system 50 design, and testament to its flexibility are our wall mounted boards.

Ideal where space is at a premium, or the need for a full switchboard with incoming protection is not necessary.

These switchboards can also be used to extend the life on an existing installation, by adding additional outgoing devices and features.

 

System 50 SlimSwitch

A derivative of our popular System 50 design, the Slimswitch variation uses ABB Slimline switches for pluggable, space efficient outgoing ways.

Extension Switchboards

Extension switchboardOur flexible range of System 50 switchboards can be supplied as an extension to an existing LVAC scheme, where columns of outgoing switches can be mated to existing switchgear to extend the life of otherwise obsolete equipment. Interconnection can be via cable or a bespoke bus-trunk solution.

Charnvel will carry out a full survey of the existing switchgear to establish the necessary connection and mechanical parameters. If detailled drawings of the existing board are not available, an outage may be necessary to carry out measurements.
