CE-B Metal Clad Switchboards

≤ 40,5kV ≤ 63kA ≤ 3.150A - 4.000A - 7.000A

CE-B Metal Clad Switchboards are designed for use in public and industrial distribution system up to 40.5kV for the operation and protection of lines, generators, transformer, motors, capacitor banks

 

 

GENERAL CHARACTERISTICS

The switchboards are composed combining the various standards cubicles.
According to the international standards IEC 62271-200 the CE-B switchboards are classified for “loss of service continuity category” as LSC2B with partition class PM (Metallic Partition) or PI (Partitions non-metallic)

Optional version A is also foreseen fully withstanding to internal arc fault IAC (AFLR)

For outdoor application the versione CE-BO is available with protection degree up to IP55 or Type 4x
