Construction characteristics
The references in round brackets
(Gx.x)
in the technical catalogue refer to the Glossary in the final charter of the
technical catalogue.
All the moulded-case circuit-breakers in the SACE Tmax XT family are realized in accordance with
the following construction characteristics:
Q
double insulation
(G1.5)
;
Q
positive operation
(G1.6)
;
Q
isolation behaviour
(G1.7)
;
Q
electromagnetic compatibility
(G1.8)
;
Q
tropicalization
(G1.9)
;
Q
impact and vibration resistance
(G1.10)
;
Q
power supply from the top towards the bottom or vice versa;
Q
versatility of the installation. It is possible to mount the circuit-breaker in horizontal, vertical, or
lying down position without any derating of the rated characteristics;
Q
no nominal performance derating for use up to an altitude of 2000m. Above 2000m, the proper-
ties of the atmosphere (composition of the air, dielectric strength, cooling power and pressure)
change, having an impact on the main parameters which define the circuit-breaker. The table
below gives the changes to the main performance parameters;
Altitude 2000m 3000m 4000m 5000m
Rated employ voltage, Ue [V] 690 600 540 470
Rated uninterrupted current % 100 98 93 90
Q
the SACE Tmax XT circuit-breakers can be used in environments where the temperature is
between -25°C and +70°C and stored in environments where the temperature is between
-40°C and +70°C. To use temperatures other than 40°C, see the “Temperature Performances”
paragraph of the Characteristic Curves and the technical information chapter;

Q
all the circuit-breakers in the XT family are fitted with a test pushbutton which allows the release
test to be done. This test must be carried out with the circuit-breaker closed and with no
current.
