1. Applicable scope
1SM1Z series of intelligent molded case circuit breaker (hereinafter referred to as circuit breakers), the company uses advanced design, manufacturing technology to meet the needs of the market development of new circuit breakers. The rated insulation voltage of 1000V, for AC 50Hz, rated voltage 400V, rated current up to 800A for the circuit for frequent conversion purposes. Circuit breaker with demand protection, overload long delay inverse time, short circuit short delay, short circuit instantaneous, ground protection, to protect the line and power equipment from damage.
Circuit breaker with power management, load limit function. Circuit breaker with small size, breaking high, short arc, with isolation, anti-vibration
And other characteristics. The circuit breaker can be mounted vertically (ie, vertical), or horizontally mounted (ie horizontal)
Circuit breaker can not be poured into the line, that is, only 1,3,5 connected to the power line, 2,4,6 then load line.
The circuit breaker is suitable for isolation, the symbol is expressed as " "
The following standards apply to the circuit breaker products: I E C 6 0 9 4 7 - 1 and GB14048.1-2006 General IEC 60947-2 and GB14048.2-2008 and Appendix F Additional tests with electronic overcurrent protection circuit breakers
Circuit breaker by the national compulsory
2. Applicable working environment and installation conditions
The installation site of the altitude of not more than 2000m; the surrounding medium temperature is not higher than +40 ℃ and not less than -5 ℃, and 24 hours of the average does not exceed 35 ℃; installation site relative humidity in the maximum temperature of +40 ℃ Not more than 50%; at lower temperatures can have a higher relative humidity, such as +20 ℃ when up to 90%, due to temperature changes occasionally produce condensation should take special measures;
The circuit breaker should be installed in the non-explosion hazard and the absence of the explosion of the circuit breaker. The circuit breaker should be installed in the non-explosion hazard and no Conductive dust, not enough to corrode the metal and damage the insulation; installed in the place where there is no rain and snow; circuit breakers should be installed according to the product instructions and wiring.
