4.1.1

Installation in the switchboard

The switchboard version and the installation and ambient conditions can have a great
influence on the ratings of the circuit breakers. The 3WL10 circuit breaker is also optimized
for advantageous switchboard integration and provides savings and reduced engineering in
respect of
● Copper busbars
● Connection architecture
● Segregation and internal separation
● Mounting options
In the following mounting conditions (see Section "Power in the switchboard"), the most
important factors have been taken into account that can affect the power ratings of the circuit
breaker in the switchboard. These factors are:
● Switchboard type
● Degree of protection of the switchboard
● Separation type 3
● Number of devices that are connected to the same switchboard panel at the same time
● Type of connection and terminal
● Ambient temperature T
● Circuit breaker with guide frame
● Maximum permissible temperature at the terminal 120 °C
