Low Voltage Distribution
Custom-built Low Voltage Switchgear engineered as the core distribution nexus of industrial installations, integrating Air Circuit Breakers up to 6300A and tested to IEC standards.
Fabricated from prime sheet steel, every metal component undergoes our rigorous 7-tank anti-corrosion chemical bath (alkali pickling, acid pickling, and hot phosphate at 70–80°C) depositing a 10–15µ phosphate barrier before electrostatic powder coating.
Electrolytic copper busbars are installed with horizontal layouts in segregated compartments at the rear or top to prevent accidental human contact and support seamless future expansion.
Engineered to withstand severe short-circuit electromagnetic stresses up to 50 kA for 1 second, reinforced by fire-retardant high-dielectric insulators.
Equipped with intelligent trip units sensitive to true RMS current values, providing overcurrent, short-circuit, ground-fault, and instantaneous protection.
Integrated digital ammeters, voltmeters with selector switches, multifunctional energy meters (kWh), and precision Class 0.5/1.0 Current Transformers.
Microprocessor-controlled breakers with true RMS current sensing for main incomers and heavy feeder protection.
High-endurance vacuum interruption technology for intensive switching operations.
Compact branch distribution and motor feeder protection with adjustable thermal and magnetic trip units.
Din-rail mounted final sub-circuit protection for lighting, instrumentation, and auxiliary power.
