K-CUBE-EJB
Description
K-CUBE-EJB X-proof integrated switchgear receives and distributes electrical power, controls electrical equipment and protects it against short circuits / overloads. The LV switchgear is used as part of power supply, control and automation as distribution switchboards, power distribution stations, control and automation panels and cabinets.
Design
1. X-proof panel
2. X-proof input breaker
3. X-proof input panel
4. Cable tray for external connections
5. SF-K-CUBE frame (purchased under a separate P.O.)
P.O. Details
The LV package may be a typical design mounted on a frame and having an input breaker, a shield, terminal boxes and an enclosure, or a kit based on the customer’s preferences.
Please use the item number from the Marking Table below in your P.O. for a typical design X-proof protection and control panel.
E.g., a P.O. for a protection and control panel K-CUBE-EJB, IIB area, 80 A input breaker, should be identified as K-CUBE-EJBIIB-80-11.

Control and automation
K-CUBE-EJB has the following types of control:
Remote control, effected remotely via an automated EHT control system;
Auto control, i.e. based on controller internal logic. In case of EHT control communication failure, the controller will interrogate the sensors and undertake control of the EHT system using the latest setpoints received prior to loss of communication.
Panel de-energizing for maintenance purposes: de-energized locally using an X-proof panel switch.
