Core Product Performance
Full digital solid-state RMS current sampling, capable of accurately measuring distorted waveform current, with high protection action accuracy, suitable for non-linear load circuits such as frequency converters and rectifier loads;
Three-stage selective protection coordination: long delay to avoid overload burning of cables, short delay to achieve hierarchical protection coordination between upper and lower levels, instantaneous to quickly cut off extremely large short-circuit faults;
Current Limiting Design, limiting peak current during short circuit, significantly reducing system short-circuit impact, protecting the rear-end electrical equipment;
Front panel replaceable rated current plug-in, no need to replace the entire circuit breaker to adjust the rated current specification, convenient for operation and maintenance renovation;
Fault Trip Indicator Mechanism, can clearly distinguish between overload / short-circuit fault types after tripping;
Fully insulated flame-retardant shell, excellent anti-vibration and temperature resistance performance, suitable for long-term continuous operation of industrial cabinets.
