Normal working condition
The MCCB applies to the following working conddition
A. Ambient air temperature ≤+40℃ and ＞-5℃
B. Altitude ≤ 2000m
C. Air relative humidity is under 50% at +40℃, it permits upper relative humidity at lower temperature, the most humid month's lowest temperature does not exceed +25℃, the month's average relative humidity does not exceed 90%.
D. Class of pollution:class 3. There are no gas and electric conduction dust which may explode, dipping and broken insulation.
E. Installation type: Ⅲ
F. The "1,3,5,N1" terminals connect with power supply, the "2,4,6,N2" terminals connect with load, can not mixed.
G. The MCCB's installing surface should upright with level, upright installing , the power supply terminal should at upside , load terminal should at underside, it also can be landscape orientation installing.
1) The products conforms to GB14048.2,IEC60497-2 standards.
2) Equipment with the protection devices.
1. Application and range of application
The NF-CS series plastic outer covering type circuit breaker (hereafter refers to as circuit breaker), is this company uses the international advanced design, one of the technique of manufacture development, development new circuit breakers. Its fixed isolation voltage is 690V, is suitable in exchanges 50Hz, fixed working voltage 400V and below.Rated current to 800A circuit as frequent changeover gum less frequent motor starter. The Circuit breaker with overload, short circuit protection device, and less voltage protection circuit and power equipment are not damaged.
