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.
