Product Description
Lighting box distribution box low voltage power supply equipment
KYN28-12 is suitable for 3.6 ~ 12KV three-phase AC 50Hz power grid, for accepting and distribution of electrical energy, and for purposes of the circuit controlling, monitoring and protection. It can be used for single busbar, single busbar section system or double busbar system, and handcart type of the circuit breaker is easy to maintain. Mainly used in power substations, industrial and mining enterprises, hotels, communities, municipal construction, and petrochemical sector as controlling protection and power distribution monitoring.
WORKING CONDITIONS
• Ambient temperature: -25ºC~+40ºC
• Altitude: ≤2000m (If it is more than 2000m, please specify when ordering)
• Relative humidity: ≤95%(+25ºC)
• Earthquake intensity: ≤8 degrees Installation Environment: In the place where there is no fire, no explosion hazards, no serious pollution, no chemical corrosion and violent vibration
