Temperature derating
The maximum permissible current in a circuit breaker depends on the ambient temperature where the circuit breaker is
placed. Ambient temperature is the temperature inside the enclosure or switchboard in which the circuit breakers are installed.The reference temperature is 30ºC

When several simultaneously operating circuit breakers are mounted side by side in a small enclosure, the temperature rise inside the enclosure causes a reduction in current rating.
You must then assign the rating (already derated if necessary according to ambient temperatuer) a downrating factor of 0.8.
Company Introduction
Wenzhou Korlen Electric Appliances Co., Ltd, It is a joint venture. My company is a manufacturer including design, development, produce and sale, professional producing MCB, MCCB, RCCB and AC contactor etc. Product enterprises. The company owns import and export power of self-run, expanding Europe and America, Middle East, Southeast Asia etc. Market, set a good Public praise.
The company have more than 1500 workers, including senior engineer among them, engineer at inside of more than 100 technician.
