Motor Control Panel is a centralized enclosure designed to house, protect, and control the circuits of one or more electric motors. Its primary function is to provide a single, safe interface for an operator to start, stop, adjust the speed, change the direction, and protect motors from various electrical faults such as overloads or short circuits.

Technical Specifications

Material Specification

§  Motor Starters:
Various types are integrated, including Direct-On-Line (DOL), Star-Delta, soft starters, and Variable Frequency Drives (VFDs).

§  Protection Devices:
Includes circuit breakers (MCBs/MCCBs), contactors, and overload relays to protect motors and circuits from faults like short circuits, overloads, and single phasing.

§  Busbars:
High conductivity copper or aluminum busbars distribute power across units, with proper insulation and isolation barriers for safety.

§  Control & Monitoring:
May include push buttons, indicator lights, ammeters, voltmeters, and, for intelligent MCCs, integrated PLCs and Human-Machine Interfaces (HMIs) for real-time monitoring and automation.

§  Cable Entry:
Provisions for cable entry are usually at the top or bottom of the panel, with ample space for termination and glands.

 Mechanical Specification

§  Enclosure and Mounting:
Floor-mounting, free-standing, metal-clad construction is standard.

§  Material and Finish:
Typically made of mild steel or galvanized steel, with a powder-coated finish for durability and corrosion resistance.

§  Construction Type:
Available in fixed-type (components permanently mounted) and draw-out type (units easily removable for maintenance without full system shutdown).

 Standard Tests

§  TTA (Totally Type Tested Assembly) IEC 61439-1&2

§  PTA (Partially Type Tested Assembly) IEC 60439
