Blokset U scheme

Blokset U scheme is applied for current less than 630A and motor protection with power less than 250kW.

Two alternatives:

Tradition power distribution and motor protection scheme

Intelligent power distribution and motor protection scheme

Applicable standard

IEC 61439-1/2 Low voltage switchgears and control device

IEC 60529 shell protection grade

IEC 60068-2-11 salt spray resistance

IEC 60068-2-30 damp heat resistance


Effective scheme

Blokset U can meet the requirements of every kind of motor protection and power distribution:

MCC: 250kW/circuit

PCC: 630A/circuit

Outstanding design makes the installation density of single cabinet higher( to 34 drawers), which can decrease the amount of cabinets and optimize invest cost.

Innovative design

Safety configuration

Specialized enclosed power distribution busbar insulation protection and shutter mechanism, complete isolation electrified to protect the safety of personnel.

1/2 drawer connects with busbar directly to avoid shunting fault of cable.

Double vertical design to increase thermal stability.
