Air Circuit Breaker Panel: 100kA Protection & Smart Monitoring

At the heart of our air circuit breaker panel is an intelligent trip unit that brings unmatched precision and adaptability to power management. This microprocessor-based device continuously analyzes voltage and current waveforms, detecting anomalies that static or thermal trips might miss. In a recent application in a paper mill in Finland, the trip unit distinguished between overload and transient faults, avoiding nuisance shuts that previously occurred monthly. It allowed the facility to set custom time-current curves via a Bluetooth-enabled LCD interface, enabling fine-tuning without opening the panel. The trip unit’s memory logs 200 event records, including the cause of trip and waveform captures, aiding rapid diagnostics. Our smart trip units also communicate via Modbus RTU, allowing seamless integration into building management systems.

Our air circuit breaker panels are built to endure the harshest electrical environments, thanks to high-grade steel enclosures and engineered breaker mechanisms. They have a short-circuit rating up to 100kA for 1 second, validated by independent testing. This robustness is vital for installations near production lines where fault currents are inevitable. The panel’s arc chute design ensures rapid arc extinction in compartments, containing events to minimal sectors. In a case with an aluminum processing plant in Canada, a 50kA fault was safely interrupted, with the panel returning to service after reset. The mechanical design allows up to 10,000 operations without significant wear, with maintenance intervals extended to every 5,000 cycles. We use anti-corrosion coatings that withstand saline and industrial atmospheres, ensuring longevity in coastal or chemical settings.
