CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
It is used as the primary switching element in medium voltage circuit breakers, contactors, and load break switches for power distribution networks, substations, and industrial facilities.
Key parameters include rated voltage, rated current, breaking capacity, contact gap, vacuum pressure, mechanical life, contact resistance, contact force, operating temperature range, creepage distance, insulation level, and weight. These must be matched to the specific application requirements.
The module references IEC 62271-100 for rated voltage, current, breaking capacity, and mechanical life; IEC 62271-1 for vacuum pressure, contact resistance, operating temperature, and insulation level; and IEC 60815 for creepage distance. Compliance must be verified with the manufacturer.
When contacts separate, a metal vapor arc forms. The arc is quickly extinguished because the metal vapor condenses on the contact surfaces and chamber walls, reducing the plasma density and interrupting current flow.
