Low Voltage Switchboard and Motor Control Center

KMCC-80A Switchboard & MCC Overview

KMCC-80A is a withdrawable low voltage switchboard up to 5000A in accordance with IEC 60439-1 standards.
The system provides motor control and power distribution functionality. KMCC-80A is a compact, flexible and reliable Low Voltage solution for applications where the supply of energy is vital for your business process. In line with form 3b and 4b, the withdrawable units can be exchanged without having to disconnect power and / or control cabling.
