BM30E series electronic plastic case circuit breaker. It is one of the new circuit breakers developed by our factory with international advanced design and manufacturing technology. Its rated insulation voltage is 800V, suitable for AC 50Hz. The rated working voltage is 400V, and the rated working current is 800A. It is used for less frequent conversion and motor starting. Circuit breaker has the functions of long overload delay inverse time limit, short short short short delay inverse time limit, short short circuit delay fixed time limit, short circuit instantaneous and under-voltage protection. It can protect the line and power equipment from damage. Circuit breakers can be classified into M type (higher breaking type) and H type (high breaking type) according to their rated limit breaking capacity (Icu). The circuit breaker has small volume and high breaking capacity. Short arc, anti-vibration and other characteristics.
Circuit breakers can be installed vertically (i.e. vertically) or horizontally (i.e. horizontally).
This circuit breaker can not be inverted into the line, that is, only 1, 3, 5 power lines, 2, 4, 6 load lines.
This circuit breaker is suitable for isolation (but different from isolation switch).
Compliance with standards
IEC 60947-1 and GB/T 14048.1 "General Provisions for Low Voltage Switchgear and Control Equipment Part 1"
IEC 60947-2 and GB/T 14048.2 "Low Voltage Switchgear and Control Equipment Part 2 Circuit Breakers"
Conditions of Use
Ambient air temperature: the upper limit does not exceed + 70 C, the lower limit does not exceed - 35 C, and the average within 24 hours does not exceed + 35 C.
Installation Elevation: No more than 2000 m above sea level
Atmospheric conditions: atmospheric relative humidity does not exceed 50% when the ambient air temperature is + 40 C, and can have higher relative humidity at lower temperatures. The monthly average maximum relative humidity of the wettest month is 90%, and the monthly average minimum temperature of the month is + 25 C, taking into account the condensation occurring on the surface of the product due to temperature changes.
Pollution level: level 3;
Installation category is: III;
Installation position should be vertical, inclination in all directions should not exceed 5 degrees.
