Description

Application The breaker is suited for distribution network of AC *0HZ, rated working current *6A—**0A, rated insulation voltage **0V, rated working voltage **0v and below. It is usde to distribute electric power and protect the line and the equipment against the damage due to overload, underd-voltage, short circuit. In normal condition, it is applied to network unfrequently switch. **0A frame size and below breakers are used to protect against motor and motor’s unfrequentl start. Breakers are designede, produced and tested according to GB******2 and relate standard. Environment conditions for operation: 1. Ambient temperature: –5&#***1; - **0&#***1;; the average value within *4h shall not exceed **5&#***1;. Attention: ambient temperature is **0&#***1; or **5&#***1;, customers should state clearly to producer. 2. Ambient temperature exceeds **0&#***1; or lower than **5&#***1;, customers should state negotiate with producer. 3. Altitude of installation place shall not exceed ***0m. 4. Relative humidity at **0&#***1; shall not exceed *0%. Higher humidity is permissible at lower temperature condition. When the highest monthly average relative humidity is *0% in the humiddest month. And the influence of dew on product surface due to temperature changes should be taken into condideration. 5. Pollution grade: grade iii. Inner component in the breaker’s pollution grade is ii. 6. Installation types: type IV for main circuit and under voltage tripped wire installation. Type III for other auxiliary circuits and control circuits. 7. Installation instruction: horizontally.
