Motor Control Centre

MCC's are used to control electric motors and other equipment's from a central location, with safety an reliability. The MCC's are available in Single Front and Double Front configuration.

MCC's are sheet steel modular construction and each vertical section is segregated with metallic barriers and are supplied in fully draw-out, semi draw-out and fixed version.

Each panels are extendable both side and can be coupled to main incomer breaker panels having higher depth either side. Double bended doors and covers ensure torsion free and self-adhesive gaskets make the panels dust and vermin proof.

Various configuration of motor starter in MCC:
  • Simple DOL starter
  • Star delta Starter
  • Soft starter
  • Variable Frequency drives

Outdoor / plant level installation can be done with double door arrangement for completely dust proof design.
