Note.
With Compact NS630b to NS1600, it is recommended to use 50 mm wideness bars (see "Recommended busbars drilling").
The following tables are based on the following assumptions:
maximum permissible temperature of bars is 100 °C b
Ti: temperature around the circuit breaker and its connections b
busbars made of copper and not painted. b
Note.
The values presented in the tables are the result of trials and theoretical calculations on the basis
of the assumptions mentioned above.
These tables are intended as an aid in designing connections, however, the actual values must
be confirmed by tests on the installation.
