A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
Tripping curves define the instantaneous trip threshold. Curve B trips at 3-5 times rated current, suitable for resistive loads. Curve C trips at 5-10 times, for inductive loads. Curve D trips at 10-20 times, for high inrush currents like motors. Choose based on load type.
Yes, they are available in 1P, 1P+N, 2P, 3P, 3P+N, and 4P configurations, and rated for 230/400 V AC, covering both single-phase and three-phase systems.
Breaking capacity indicates the maximum short-circuit current the breaker can safely interrupt. For these breakers, it ranges from 6 kA to 10 kA. Ensure the prospective short-circuit current at the installation point does not exceed this value.
Check the rated current, voltage, breaking capacity, tripping curve, number of poles, and other parameters against your system requirements. Always consult the manufacturer's datasheet and confirm compliance with relevant standards like IEC 60898-1.
