5.14.1. Striker activation
It requires the use of SIA-C models with trip output for striker (SIACXXXX0XXXXX,
SIACXXXX1XXXXX and SIACXXXX4XXXXXX).
The activation of the SIA-C trip output means that a capacitor has discharged on the output
terminals. This discharge of energy is sufficient to activate a striker that mechanically acts on a
mechanism to open the current circuit. The striker is connected directly to the SIA-C output,
which supplies sufficient power to activate it (24 Vdc
– 135mJ).
The striker is a bistable device with a simple action. The striker shaft is moved by a spring. The
striker is activated by a polarized low-power electrical signal, supplied by the relay if a fault
occurs. Resetting the shaft to its position is done manually. Resetting the striker has to be done
in such a way as to guarantee that the opening mechanism is closed. This is normally done
manually.
As an example, the characteristics of the striker on the image are next:

Travel:...........................................8m

Strength of the spring:

Start of travel: ...........................37 N

End of travel:
............................18 N

Response time:..............................4 ms

Level of protection:.......................IP-40
Due to the existing variety in the market, it is important to check the voltage and the necessary
energy for its activation. Some examples are shown next:
