UEM5 AC MCCB Product Characteristics
AC MCCB Characteristics 1
– The base, cover, shaft and other insulating parts are pressed by IDI company’s thermosetting composite material, with high strength and high insulation performance, so that the performance of the AC MCCB circuit breaker is reliably guaranteed.
– UEM5 AC MCCB Advanced and reasonable operating mechanism design, fast breaking speed, small tripping force. The use of “two-step breaking system” not only reduces the volume of the circuit breaker, reduces the cost of the product, but also meets the high voltage performance and high short circuit breaking capacity, so that the dual combination of economy and practicality.
AC MCCB Characteristics 2
– Contact system adopts electromagnetic repulsion current limiting principle. When the fault current is generated, the electric repulsion force makes the static and static contacts repulsion quickly. The company’s unique patented technology is used to lock the moving contacts, increase the opening distance to avoid arc reignition, so as to achieve the purpose of current limiting and improve its breaking ability.
– The AC MCCB circuit breakers with different breaking capacity levels of M, H and R of the same shell frame grade have the same outline size and installation size, which greatly improves the interchangeability.
AC MCCB Characteristics 3
– Box accessories (including shunt release, undervoltage release, auxiliary contacts, alarm contacts) are designed to ensure flexibility in control functions. The user does not need to disassemble the cover to install directly, and there is no need to adjust the installation. The safety of operation is improved due to the insulation box design.
-UEM5L AC MCCB circuit breakers with residual current protection have reliable low voltage protection, and the line voltage is as low as 50V to ensure the reliable operation of residual current protection function. The same product not only the remaining action current is adjustable, but also the action time is not delayed and the delay is adjustable.
AC MCCB Characteristics 4
– Full range of rated insulation voltage up to 800V, rated impulse withstand voltage up to 8000V, to achieve high reliability and high safety.
– The use of excellent electrical properties of alloy material dynamic contact, to ensure high mechanical and electrical life.

Standard operating environment and installation conditions
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.
