Product Overview
The KP-DW45 intelligent air circuit breaker is mainly used to distribute electric energy and protect circuits and power-supply equipment from overload, undervoltage, short-circuit and single-phase earthing. With intelligentized and selective protection functions, it improves the reliability of power supply and avoids unnecessary power failure.
Product Features
・Rated AC current: 630A – 6300A
・Short-circuit breaking capacity: 80kA – 120kA
・Rated voltage: under AC 690V
・Intelligent selective protection
