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.

3. Model and meaning

(100A (40A ~ 100A), 225A (90A ~ 225A); 1SM1Z -400 for the 400A (160A ~ 400A); 1SM1Z -630 for the 630A (252A ~ 630A), 1SM1Z -200 for the 40A (16A ~ 40A) ); 1SM1Z-800 for the 800A (320A ~ 800A). According to the wiring method is divided into the board before the wiring, board wiring, plug-in board before the wiring, plug-in board after the four; according to whether the circuit breaker with accessories with accessories and accessories without accessories: Annex internal and external accessories: Accessories are shunt release, undervoltage release, auxiliary contact, alarm contacts four;
