Application Scope
● The CDW3V series molded case circuit breakers have a rated current from 400A to 6300A and a rated voltage of AC 220V/230V/240V/380V/400V/415V/440V/480V/500V/525V/550V/660V/690V. They are suitable for AC 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 circuit breakers are widely applicable in power stations, factories, mines, modern high-rise buildings, and especially in smart building power distribution systems.
