Application Scope
● The CDW6i series air circuit breakers cover rated currents from 400A to 6300A and rated AC voltages from 415V to 1150V. They are suitable for 50/60Hz power systems, primarily used in distribution networks to distribute electrical energy and protect circuits and power equipment from overload, undervoltage, short-circuit, single-phase grounding, and other faults.
● These breakers are widely applicable in power plants, factories, mines, modern high-rise buildings, and especially in smart building distribution systems.
