Wholesale Price China Earth Leakage Circuit Breaker - ZGLEDUN Series LDM9L-(CM1) MCCB molded Case Circuit Breaker, RCCB Residual Current Residual Current operated Cicuit-breaker with Integral Overcurrent Protection RCBO – Elemro

Product Description:

Circuit breakers are classified into M type (Medium high breaking type) and H type (high breaking type) according to their rated limit short-circuit breaking capacity (Ieu). This molded case circuit breaker has the characteristics of small size, high breaking, short arcing, and anti-vibration.

This MCCB can be customized to suit your needs.

Normal Working Conditions

◆Ambient medium temperature: not higher than +40℃ (+45℃ for common products) and not lower than -5℃. The average value of 24h does not exceed +35℃ (+40℃ for common products )
◆ Installation location: The altitude does not exceed 2000m;
◆ Installation location: The relative humidity of the air does not exceed 50% when the highest temperature is +40℃. It can have a higher relative humidity at a lower temperature. For example, relative humidity 90% at 20℃. Special measures should be taken for suspected exposure occasionally due to temperature changes.
◆ Installation category:
Main circuit of the circuit breaker and the undervoltage release: Grade III
Auxiliary circuits and control circuits: Grade II
◆ The circuit breaker can withstand the influence of humid air, salt mist, oil mist, mold and nuclear radiation.
◆ The maximum inclination of the circuit breaker installation is ±22.5°
◆ The circuit breaker can work reliably under earthquake conditions (4g);
◆ The circuit breaker should be installed in a place where there is no danger of explosion, no conductive dust, no corrosion of metal and no damage to insulation.
◆The circuit breaker should be installed in a place where there is no rain or snow.

Classification of Circuit Breaker

• Type A: The N pole is not equipped with an overcurrent release ( Shunt Trip ). The N pole is always on, and it is not switched on/off together with the other three poles.
• Type B: The N pole is not equipped with an overcurrent release ( Shunt Trip ) and is switched on/off together with other three poles (N pole is closed first and then opened).
• Type C: The N pole is installed with an overcurrent release ( Shunt Trip ) , and is switched on/off together with the other three poles (the N pole is off first and then on).
• Type D: N pole is installed with an overcurrent release ( Shunt Trip ) . The N pole is always on, and it is not switched on/off together with other three poles.
