(Holidays round) ▂▂▂▂▂ ● Description: molded case circuit breakers, the situation in the circuit as connected, breaking and carrying rated current, and can load overload, short circuit, undervoltage under reliable circuit protection. Moving the circuit breaker, the static contact and contact bar is designed to parallel form, the use of short-circuit electric repulsion dynamic and static contact disconnect, high breaking capacity, limiting characteristic strong. ▂▂▂ ● use NSE series molded case circuit breakers for AC 50 / 60HZ, rated working voltage 690V, rated current of 15 to 630A distribution network for the distribution of power and protection circuits, power supply and electrical equipment against overload and short-circuiting hazards. Improve power supply reliability and continuity. ▂▂▂▂▂▂ ● ● national standards in line with standards: IEC 947-1: General (GB / T14048.1) IEC 947-2: Circuit Breaker (GB / T14048.2) IEC 947-4: contactors and motor Launcher (GB14048.4) IEC 947-5.1: control and switching equipment, automatic control element (GB14048.5) ▂▂▂▂▂▂ ● Kangshire measures NSE breakers and anti-assist device T2 hot and humid conditions, the implementation of the following criteria: IEC68-2-30 at 45 ℃ 95% relative humidity (hot and humid climate) IEC68-2-11 salt spray test ▂▂▂▂▂ ● isolation all NSE breakers are suitable for isolation, in line with IEC947-2 standard contacts isolated position in the "O" (OFF position) unless the contact is fully open, the operating handle can not be "OFF" position contacts are open, we can extend the rotation handle installation padlock does not change the position indication system reliability ▂ ▂▂▂▂▂▂▂▂▂▂▂▂▂ ● isolation test with guaranteed warranty guaranteed by the position indication system reliability without mechanical contact leakage current overvoltage tolerance refers to the withstand voltage between its inlet and outlet of the ability ▂▂▂▂▂▂▂▂▂▂▂ ● product attribute normal working conditions: ambient air temperature limit + 40 ℃; ○ ambient air temperature limit -5 ℃; 24h average of ambient air temperature does not exceed + 35 ℃. Elevation above sea level, the installation site does not exceed 2000m.
