Contact S51/P1
PR332/P and PR333/P have an external contact, which can be configured by the customer and is useful for monitoring a series
of events, including alarms and protection trips
The configuration options of the contact, available via PR010/T or Ekip Connect, are:
- Monitoring event/s;
- Contact activation delay;
- Idle state (normally open or closed);
- Trigger configuration (Auto or Single).
The parameters are available in the Settings-Modules-SIGNALLING module-Relay.
The contact is available in all supply configurations and possesses the following electrical characteristics:
Type of contact
Maximum switching voltage
Maximum switching current
Maximum switching power
Contact/Circuit insulation
NOTE: contact S51/p1 is not available for release PR332/P MM.
3.8.6.
Function MM
PR332/P MM has a pair of input and output contacts for managing protection MM, described on page <OV>:
- K14/K15: input for activating protection MM;
The voltage applied between K14 (+) and K15 (-) establishes the state of the protection:
- 0..2Vdc protection deactivated.
- 15..24Vdc protection activated.
Consumption @24Vdc= 3mA max.
- 95S/98S: the output supplies the state of protection MM:
- If the protection is active, the contact is closed;
- If the protection is deactivated, the contact is open.
The electrical characteristics of the output contact are the same as those of contact S51/P1, described in the previous chapter.
Operation of the output contact is guaranteed when the release is on, in the Full Power mode or in the presence of auxiliary supply.
WARNING:
-Upon powering, and if there is already energizing voltage on the input contact, the output contact closes within 100 ms.
-Following a trip through protection MM, the output contact can open temporarily for up to 20ms.

Circuit-breaker
This area allows you to:
- Enable the Neutral protection (ON/OFF) and adjust its control level (50%- 100% - 200%). All the details about the operating
mode are given in the description of the Neutral protection, in par. 1.6.20.
- Enable the presence of a sensor on the earth protection line (SGR or Rc). A further option for selecting the sensor model
(100,250,250,800) will be available if the selected sensor is the SGR type. Functions and case reports on use of the earth pro-
tections are illustrated in the chapters that describe protections Gext (par. 1.6.9) and Rc (par. 1.6.10).
- Perform the installation and uninstalling operations for the protection release in the CB. Instructions for correct installation are
given in par. 1.12.1 and 1.12.2.
