PCC PANEL

• PCC (Power Control Centre) Panel specifications cover electrical ratings (Voltage 415V, Current up to 6300A), construction (CRCA MS, IP rated for dust/vermin proofing), components (MCCBs, Busbars of Copper/Aluminium), and protection features (Short Circuit capacity 50kA+, Insulation Voltage 660V), ensuring safe power distribution with modular, robust, and maintainable designs. Key specs include operational current, short-circuit withstand, IP rating, busbar material, enclosure type (cubicle/floor-standing), and internal components like meters, relays, and MCCBs. 

Operational Voltage: Typically 380/415/440V, 3-Phase, 4-Wire.

Rated Current: Varies by application, often up to 6300A (e.g., 1000A, 2000A, 4000A, 6300A).

Insulation Voltage: Up to 660V.

Short Circuit Withstand: 50kA for 1 second (or higher, e.g., 50-100kA).

Frequency: 50 Hz. 

Material: CRCA (Cold Rolled Close Annealed) MS Sheet (1mm to 3mm thick), sometimes SS or Aluzinc.

Type: Cubicle, floor-standing, single/double front, fixed/semi-draw-out.

Degree of Protection (IP Rating): IP4X, IP5X, IP54, IP65 (dust & vermin proofing).

Painting: Powder coating (60-80 microns).

Gasketing: Synthetic rubber/neoprene for IP rating. 

Busbars: Electrolytic Copper or Aluminium, sized for current density (e.g., 1A/sq.mm Al, 1.6A/sq.mm Cu).

Circuit Breakers: MCCBs (Molded Case Circuit Breakers) for incoming/outgoing feeders, sized appropriately.

Metering: Digital Multifunction Meters, KWH meters, Ammeters, Voltmeters (Class 1 accuracy).

Protection Relays: REF Relay, VMR, AMF Relay.

Indicating Lamps & Switches: Phase indicators, selector switches.

Wiring: Copper flexible wires, sleeved lugs, ferruled, color-coded. 

Modular/Non-Compartmentalized: For flexibility.

Extensible: Provision for future expansion.

Maintenance: Easy access for inspection, repair, with earthed barriers for safety. 

Designed to IEC/IS standards (specifics vary by project).
