5.14. Opening mechanism
The type of trip is selected by model: SIACXXXX0XXXXX, SIACXXXX1XXXXX and
SIACXXXX4XXXXX are provided with a polarized trip and models SIACXXXX2XXXXX and
SIACXXXX3XXXXX are provided with a simple trip:
Polarized . The trip is associated to a striker. The type of trip is a polarized trip, this is, the trip is
associated to a striker. There are a lot of models of strikers in the market, with different trip
energies, being for example 50 mJ (0,05W·s) and operation voltage of 6V, or 135 mJ (0,1W·s)
and operation voltage of 24V.
The opening mechanism is activated by means of a striker. The activation of the trip generates
a pulse train.
The Trip Voltage Level setting allows adjusting the trip voltage level required by the selected
striker. The default value is 17 Vdc, although there are several options:

12 Vdc

17 Vdc

22 Vdc

24 Vdc
The equipment will allow the trip when it gets the selected trip voltage, so if a lower level that
the required by the striker is adjusted, it may result on tripping without enough energy and not
activating the striker.
On the other hand, if a higher level that the required by the striker is selected, the activation of
the striker is guaranteed, however, the fault trip time during start-up may be increased. Fanox
encourages selecting the correct value of this critical setting and offers its expertise at any
doubt.
Simple . The equipment closes a free potential contact and there is an external element which
accumulates the trip energy, in capacitors or batteries. (Not used for relay power supply, only
for the trip).
The opening mechanism is activated by means of a striker or a coil. The activation of the trip
generates a pulse train. The equipment SIA-C solves the next situations during the activation of
the opening mechanism:

Striker activation

Coil activation by means of a free potential contact

Coil activation by means of the TCM adapter
