The Heart of Your Electrical Infrastructure

Our Main Distribution Boards (MDBs) are the primary point for power entry and distribution within a facility. Engineered for maximum reliability and safety, these panels receive bulk power from the transformer and distribute it to various sub-panels and heavy machinery, ensuring a stable and protected electrical network for industrial plants, skyscrapers, and commercial hubs.

• General Description: A high-capacity, modular power distribution system designed to manage large electrical loads. As a certified manufacturer, Square EIC builds these panels using world-class components (such as Schneider Electric or ABB), ensuring they serve as a robust barrier against electrical faults.

• Key Technical Specs:

  • Rated Operating Voltage: Up to 690V.

  • Rated Current: From 630A up to 6300A.

  • Short-Circuit Withstand: High-capacity designs up to 100kA for 1 second.

  • Ingress Protection: Available in IP42, IP54, or IP55 for indoor environments, and specialized IP65 for outdoor applications.

  • Form of Separation: Available in Form 2, Form 3, and Form 4 (up to 4b) to ensure maximum safety for operators during maintenance.

• Engineering & Design:

  • Busbar System: High-conductivity, high-purity electrolytic copper busbars, precision-sized to prevent overheating and withstand electromagnetic stresses during short circuits.

  • Modular Architecture: Floor-standing, extensible cubicle designs that allow for future expansion or the addition of extra feeder sections.

  • Circuit Protection: Equipped with Air Circuit Breakers (ACBs) for main incoming/outgoing lines and Moulded Case Circuit Breakers (MCCBs) for sub-feeds.

• Advanced Monitoring:

  • Power Quality: Integrated digital power meters for real-time monitoring of voltage, current, harmonics, and power factor ($cos \phi$).

  • BMS Integration: Fully compatible with Building Management Systems via Modbus, Profibus, or Ethernet communication protocols.

Why Choose Square EIC MDBs?

1. Type-Tested Reliability: Our panels are manufactured in strict accordance with IEC 61439-1 & 2, ensuring they meet international standards for temperature rise, dielectric properties, and short-circuit resistance.

2. Safety First: Features like mechanical interlocks, insulated busbar shrouding, and dedicated earthing systems minimize the risk of accidental contact or arc flash.

3. Thermal Management: Optimized ventilation systems and integrated cooling fans ensure that components operate within their ideal temperature range, extending the lifespan of your switchgear.
