1. Application of S moulded case circuit breaker

The S series moulded case circuit breaker applies to breaking and making operation in AC 50/60Hz, rated operation voltage 690V or less and rated current up to 2000A circuit. It can distribute electric energy in circuit, work as the overload of wiring and power supply equipment, or as the protector of short circuit and under voltage. Additionally, this breaker can switch line and start motor unfrequnently. The other characters of the products are: small size, large contact spacings, high capability of break-make, and short arcing distance, this performance is better than that of CM1 series.  This performance is as well as original S series circuit breaker. The product complies with the standards of IEC90947-2.

2. Working Circumstance of S moulded case circuit breaker

1). Altitude of the installation place shall not be higher than 2000m(in case it's higher, do ask for advice
from manufacturer first)
2). Circumstance temperature shouldn't be higher than +40℃ or lower than -50℃ , average temperature of
24h shouldn't exceed +35℃ .
Attention: If temperature breaks the limits issued above, users shall operate the product according
to manufacturer's advice.
3). Working area shall not contain any explosive, metal corrosive or inductive media, the place also
should weatherproof.
4). Relative atmosphere humidity shall not exceed 90% 
5). Working place shouldn't be shaky or exposed to rain & snow, connect upper terminals to power
source while lower terminals to load, inclination on each side shall not exceed 50.
