5 Characteristics the signalling contacts
The following data are defined for resistive loads
Type contact SPST
Max switching voltage 130 VDC 380 VAC
Max switching current A
Max switching power 175 2000 VA
Breaking capacity VDC ---
Breaking capacity 120 VDC 0.3.
There are two possible configurations for the SIGNALLING module:
- default configuration: digital input, contacts with pole common, independent contact;
- alternative configuration: independent contacts.3.

The digital input activated 24VDC 20% voltage.2 Front view
- "Power" LED (lit when Vaux PR120/V PR120/LV are installed)
- LED: associated with the signalling contacts.
For the load control function, the module can used actuator.3.

The two configurations are alternative each other.1 General characteristics
The module enables the local signalling alarms and circuit-breaker trips.3.4 Characteristics the digital input
The unit enables the digital input associated with the following functions:
- enabling alternative set parameters, set (PR123/DC only);
- outside trip control;
- zeroing release trips;
- resetting PR120/K contacts;
- local/remote enabling;
- resetting energy meters.3 Releases complete with the module
- optional for PR122/DC
- optional for PR123/DC
