Environment temperature
 
HDM3 series can work for a long time under normal environment and operating temperature between -5°C and 50°C .

Altitude
 
Altitude at normal installation site does not exceed 2000m.

If the altitude exceeds 2000m, the changes in the dielectric strength and the air temperature drop must be considered. Refer to the altitude derating factor table or contact us.

Humidity
 
The following conditions must be met during normal operation:

The relative humidity of atmosphere does not exceed 50% if the ambient air temperature is +40°C .The product can be used at a high relative humidity if the temperature is low.

The monthly average relative humidity at the wettest month is 90%.

The impact of the condensation generated on the product surface on the product property shall be considered.

Reliable contact indication with isolating function

HDM3 moulded case circuit breaker complies with the isolation defined in IEC standard 60947-2

The isolated location corresponds to O (OFF)

The operating handle can indicate “OFF" only when the contact is really open

The rotation handle or electric operating mechanism will not change the reliability of the contact indication system.Through the test, the isolating function must guarantee:

Mechanical reliability of contact indication system

No leakage current

There is a certain overvoltage resistance capacity between the input and output terminals.

Protection class

IP protection class of circuit breaker body: IP20 · Circuit breaker installed in the switch cabinet:

circuit breaker with a toggle handle IP40

circuit breaker with an electric operating mechanism IP40
