Product Description
UEM5L MCCB RCD Circuit Breaker
UEM5L MCCB RCD Circuit Breaker is suitable for AC 50Hz/60Hz, rated current from 10A to 1600A, rated insulation voltage of 800V, rated working voltage of 690V and below the low-voltage power grid, with overload, short circuit and undervoltage protection function.
UEM5L MCCB RCD with residual current protection circuit breakers provide protection against dangerous voltages caused by insulation damage, and can also provide protection against hazards such as fire caused by insulation damage.
UEM5L MCCB RCD Product Characteristics
-Insulating parts such as base, cover and shaft are made of thermosetting composite materials, which have high strength and high insulation performance.
-MCCB RCD unique contact design, fast breaking speed and small tripping force.
-MCCB RCD rotating flip structure, easy to install accessories without opening cover.
-MCCB RCD adopt advanced electromagnetic repulsion technology to quickly extinguish the arc.

Standard operating environment and installation conditions
Leakage Circuit Breaker Operating Temperature:
– The reference operating ambient temperature of the thermal element with the thermal magnetic overcurrent release is set to +40 ° C
– Between +40°C and +70 °C, due to the temperature characteristics of the bimetal sheet of the trip device, the thermal trip value must be reduced
– Thermal trip value can be increased when below +40°C
– The performance of the microprocessor overcurrent release does not fluctuate due to the change of temperature, but when the temperature is higher than +40°C, due to the current in the circuit breaker
– The copper parts (moving and static contacts and connection terminals) flowing through will undergo some changes that will cause the rated continuous current to be reduced, and the maximum set value of the overload protection function will need to be reduced
– The performance of the circuit breaker cannot be guaranteed when the ambient temperature is higher than +70 ° C.
-In order to ensure the continuity of the work of the power equipment, it is necessary to consider keeping the temperature at a temperature where all the equipment can work normally, rather than only considering the operating temperature of the circuit breaker, such as taking strong ventilation in necessary occasions.
Altitude:
-Above 2000 m, with the increase of altitude, the composition of the atmosphere, insulation properties, cooling properties and air pressure change. At this time, the performance of the circuit breaker will be reduced, mainly in some major parameters, such as the maximum operating voltage and rated operating current and dielectric strength.
