A pre-assembled electrical panel contains all the necessary elements of the General Protection and Control Box (GPCB). In other words, it includes all the electrical protections necessary to protect against direct and indirect contacts, in a box ready for installation. For single-phase supplies they can be basic electrification (from 5750W to 7360W) or high electrification (from 9200 to 14490W), depending on their power they will use a different IGA (Circuit Breaker) calibre. All the necessary information to know the protection number and which ones to use in our CGPM can be found in the ITC-BT-25.
