temperature of +40 ℃. The higher relative humidity is allowable at
the lower temperature. The lowest monthly average temperature not
higher than 25 ℃ in the most moist month and the max relative
humidity should be no more than 90%.
D. Pollution degree:Grade 3. Three is no explosion factor,
corrosive metal and the gas destroying the insulation and the
electric dust.

What is the difference between Plug-in and Fixed Circuit Breaker ?
The plug-in version makes it possible to:
- Extract and/or rapidly replace the circuit breaker without having
to touch the connections on the base
- Allow for the addition of future circuits by installing bases that
will be equipped with a circuit breaker at a later date
- Isolate the power circuits when the device is mounted on or through
a panel. It acts as a barrier for the connections of the plug-in
base. Insulation is made complete by the mandatory short terminal
shields on the device.The degrees of protection are: circuit
breaker plugged in = IP4
circuit breaker removed = IP2
circuit breaker removed,base equipped with shutters = IP4.
