Type MBS / MBD Motor Control Centres (MCC) are of bolted construction and designed to meet the requirements of modern Power & Steel Plants, Refineries and other Engineering & Process industries. These conform to IS 8623 and IEC 439.
MCC can be offered in single front or double front execution in fully drawout or non-drawout design, conforming upto IP 54 degree of protection. Busbars are designed upto 5000A rating and 65 kA fault level for 1 sec.
Vertical busbars are designed for 4 pole plug-in system to provide drawout isolation of neutral. Frames of panel are made of formed profiles and bolted together using tool based connecting pieces, resulting in high accuracy.

Non-hygroscopic fire retardant FRP barriers and moulded DMC / SMC insulators for the busbars for increased safety.
High contact pressure for drawout power contacts of silver-coated copper.
Sliding type, sturdy, silver-coated control contacts for safe operation and easy maintenance of drawout MCCs.
First-to-make, last-to-break scraping earth provided on each drawout tray for safety to operating personnel.
Spacious cable chambers (300mm) to facilitate easier cable terminations.
Vertical busbars designed for 4 pole plug in system to provide drawout isolation of neutral thus avoiding neutral links.
Standardised compartment and tray sizes for interchangeability.
