Use and Maintenance
Various characteristics and accessories of the circuit breaker shall be fixed by the manufacturer and shall not be adjusted in the use. Under the compliance with custody and use conditions, from the date of 24 months from the manufacturer delivery and in the situation of the circuit breaker intact seals, if the product is damaged or not used normally due to manufacturing quality problems, the manufacturer shall be responsible for replacement and repair without charge.

Applied Environment
1. The altitude is not higher than 2,000 m;
2. It is resistant to damp air (three-proof type)①
3. It is resistant to the influence of salt fog and oil fog (three-proof type);
4. It is resistant to the influence of mold (three-proof type);
5. In a medium without explosion risk, the medium is not enough to corrode the metal and destroy the insulation of the gas and conductive dust.
Note: the three-prevention products should be specially customized, please indicate TH.
