PROTECTION RELEASES PR332/P AND PR333/P

3.1. Introduction
PR332/P and PR333/P possess many common characteristics:

- Graphic interface: display, push-buttons and interactive menu.

- HW: connectors and accessory modules.

- SW: basic protection and measuring functions.

Unless different indications are given, the functions and characteristics described in the following chapters are common to both

models.

3.2. Overview
PR332/P and PR333/P are available in 7 versions, all compatible with various different internal modules, external accessories

and testing devices:

3.3. Specifications
Protection releases PR332/P, for SACE Emax X1 and SACE Tmax T7-T8, circuit-breakers, and PR333/P for X1 circuit-breakers

are electronic devices with functions for monitoring and for protecting against fault currents.

The units also possess Measuring, Data Storage, Communication, Self-diagnosis, Load Control and Zone Selectivity functions.

The protection release installed in the circuit-breaker is connected to the current sensors for primary current reading, to the Trip

Coil for the circuit-breaker opening command and to the CB state contacts.

The sensors provide the primary current measurement and energy for powering the protection release even in the absence of

external power supply.

Connected directly to an opening mechanism, the Trip Coil allows the CB to open. The command is transmitted to the Trip coil

in accordance with the protection settings.

The state contacts of the CB provide information about the CB's position.

A graphic display and a set of push-buttons allow all the information about the protection release to be accessed. They can also

be used for adjusting the protections and settings and for reading the state and alarms. In addition, the presence of alarms is

indicated by two front leds.
