Product Features

SX series molded case circuit breakers are classified into four types according to their rated limit short circuit breaking capacity (Icu): C type (economical), S type (standard type), M type (high breaking type) and H type (high breaking type). The circuit breaker has the characteristics of small volume, high breaking capacity, short arcing distance and vibration resistance. There are two forms of short-circuit current protection (magnetic) and over-current protection (thermal).

SX series plastic case circuit breaker arc-free series adopts CDC arc-extinguishing technology, which has the characteristics of zero arc-extinguishing distance, and is especially suitable for drawer-type and closed complete equipment with compact structure.

SX series molded case circuit breakers are quickly installed with boxed accessories, and users can respond in time without adjustment.

Applicable Conditions

1. Ambient temperature:-35℃ ~+70℃ (special ambient temperature can be specially customized);

2. Altitude: The altitude of the installation site is not more than 2,000 m, so users at high altitude need to reduce their capacity.

3. Atmospheric environment: the relative humidity shall not exceed 50% at +40℃ and 90% at +20℃;

4. Earthquake intensity: no more than 8 degrees;

5. The product is installed in a medium without explosion danger, and the medium is not enough to corrode metals, gas and conductive dust that damage insulation, and avoid being used in places where rain and snow attack;
