Key Features & Benefits
Electrolytic-Grade Copper Busbars: Tin-plated C11000 copper busbars rated for a 100% continuous ampacity load, minimizing I²R thermal losses and voltage drop.
Modular Distribution Layout: Accommodates DIN-rail mounted miniature circuit breakers (MCBs) and molded case circuit breakers (MCCBs) for scalable branch-circuit configuration.
Integrated Branch-Circuit Monitoring: Real-time metering modules capture voltage, current, frequency, and active energy (kWh) with RS-485 Modbus RTU communication protocols.
Heavy-Duty Enclosure Integrity: 2.0mm cold-rolled steel frames treated with a multi-stage phosphate wash and electrostatic epoxy powder coat (RAL 7035 structure finish).
Thermal Management Design: Optimized internal baffling and optional top-mounted exhaust fan trays maintain operating temperatures within 40°C ambient thresholds.
