Notes
1)
Permissible continuous current for circuit-breakers operating in switchboards at various internal ambient temperatures.
The switchboard’s internal ambient temperature should be estimated using the calculation methods of IEC regulation.
2)
Rated continuous current stated applies only with 4 x 120 x 10 mm vertical terminal rails painted black.
The values are reduced by 100 A each with 4 x 100 x 10 mm.
