Product Description
UEM5DH MCCB Breaker Characteristics
UEM5DH MCCB Breaker Characteristics 1
– The electric arc will be rapidly extinguished due to advanced “magnetic blow-out” technology and special contact design.
– MCCB breaker thanks to advanced “air-blowing” technology and special material used for arc extinguishing chamber, the electric arc will be conducted into the chamber rapidly.
UEM5DH MCCB Breaker Characteristics 2
– The direct current is reliably interrupted and higher electrical endurance ensured due to special arc extinguishing system and cross arrayed arc extinguishing grid.
– MCCB breaker effective use of the arc extinguishing chamber space enlarges the gap between the contacts, which can lengthen the arc much faster thus turning it off.
UEM5DH MCCB Breaker Characteristics 3
– This MCCB breaker can be equipped with shunt release, auxiliary contact, alarm contact, motorized operating and manual operating mechanism.
– The MCCB breaker design of cassette-type accessories ensures fast and reliable accessory installation.
UEM5DH MCCB Breaker Characteristics 4
– The positive and negative electrodes of the incoming line terminal are reversible, making the wiring convenient.
– Different wiring method (down in and down out/up in and down out) makes the wiring flexible.

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 circuit breaker cannot be guaranteed when the ambient temperature is higher than +70 ° C.
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.
