Tooth caps
The caps block off the reserve terminals on a
Linergy FC distribution block.
Made of an insulating material, they simply clip on
from the front.

Characteristics
Common characteristics
Rated operational current at 40° (Ie)
Distribution-block derating follows the normal
derating curves of Compact NSX and INS
Rated conditional short-circuit
current of an assembly
(Isc)
The reinforced breaking capacity due to cascading
in circuit-breaker combinations is maintained.
The worst-case situations have been tested.
The electrical characteristics are perfectly
compatible with the connected devices.
Neither the temperature derating curves nor the
performance levels of the circuit breakers and
switch-disconnectors are altered.

Linergy FC selection table for special cases
For most installations, the temperature around the switchboard is 40 °C,
corresponding to an average temperature of 60 °C inside the switchboard.
Under certain conditions, the temperature inside the switchboard may be different.
