NA8G Electric Fixed/Drawer Air Circuit Breakers For Equipment Line Protection
Product Description:
The NA8G series air circuit breaker (“circuit breaker” in short), with rated current from 200A to 6300A and rated operating voltage of 415V, 690V AC, is suitable for operation under 50Hz/60Hz AC and is mainly used in distribution network for power distribution, and to protect power line and power equipment from various faults such as overload, short circuit, undervoltage and single-phase ground. The circuit breaker is a combination of aesthetic appearance, high breaking capacity,zero flashover and multiple intelligent protection features . It can provide selective protection with accurate operations, to avoid unnecessary black out and guarantee reliable power supply.
Standard:IEC/EN 60947-2.
Operating Conditions and Environmental Suitability:
NA8 products can operate normally at the following temperature.
Electric and mechanical characteristic applicable for ambient temperature -5℃~+40°℃(certified), and also peripheral ambient temperature -45℃~+70℃(M type ), -20℃~+70℃(H type ).
Storage conditions: Applicable for -45℃~+70C.
NA8 may resist against the following electromagnetic interference: EMI-generated overvoltage; Overvoltage caused by environmental disturbance or distribution system; Radio wave (radio, interphone,radar, etc.).
Static discharge of terminal users NA8 circuit breakers have successfully accredited through the EMC test specified in the following standards: IEC/EN 60947-2.
The above tests may ensure: no false tripping fault, tripping time not interrupted.
Protection grade: Front IP20,other sides IPO0
