2.3.3 Load current
The rated normal currents listed in Table 1 have been laid
down for an ambient temperature of 40°C. The
maximum permissible load current as a function of the
ambient temperature of the 3AF 01 circuit-breaker has
been plotted in Fig. 4.
2.4 Service life
Under normal operating conditions, the circuit-breakers
are designed for 10,000 mechanical operating cycles.
Due to the optimization of the service life of all parts, the
level of reliability falls if the breakers are used for a
greater number of operating cycles. The manufacturer
can therefore not recommend continued use of the
circuit-breakers, even if certain subassemblies are
renewed.
When the permissible maximum has been attained, the
complete pole assemblies must be renewed. Detailed
instructions are supplied with the replacement pole
assemblies.
When ordering replacement pole assemblies, state the
circuit-breaker type, design code and serial number (see
name plate).
2.5 Fixing/termination dimensions and weights
The dimensions of the vacuum circuit-breaker are shown
in the relevant drawings which can be ordered through
Siemens office.
The weight can be found on the breaker name plate, in
Table 1 or in the relevant General Assembly drawing.
