ABB PR122/P-LI E1-E6 Low voltage power circuit-breakers

Relay PR121/P is an electronic unit for Emax CB. Its function is to monitor and protect against abnormal current.The unit installed on the CB is connected to the current sensors for primary current reading and to the Trip Coil for circuit-breakeropening control.The sensors provide the primary current measurement and the energy for powering the relay, even in the absence of externalpower supply.Connected directly to an opening mechanism, the Trip Coil allows the CB to open. The control is transmitted to the Trip coil inaccordance with the protection settings.Dip switches on the front allow the main protections and settings to be regulated, while the state of the relay is indicated by theleds of the front interface.

A set of accessories adds optional functions to the basic version.Temporary accessories:- PR030/B powers the relay so as to display its state (by means of the LEDs) and allow the installation operations to be performed.- BT030-USB for relay powering and communication, so as to allow different sorts of information to be supervised via a PC, suchas the Trip and measurements log fi le, and for regulating settings and functions that cannot be adjusted by means of the frontdip switches, such as the Thermal Memory.- PR010/T allows the relay to be supplied, enables the protections to be tested and test reports to be saved.- Ekip T&P, similarly to BT030-USB, can be used to power and communicate with the relay via a PC. It also allows units likePR010/T to be tested, again via a PC.Communication with ABB SACE devices is facilitated by the Ekip Connect SW supplied with BT030-USB and Ekip T&P modules,or available from the Internet website.Fixed accessories:- The HMI030 panel interface expands the monitoring functions of the relay and displays the current measurements of all thephases in real time.- Flex Interface modules allow the alarm or state signals of the relay to be matched to programmable electromechanical contacts.They also allow a complete network of several units to be created and can also be connected to external modules (e.g. HMI030).Consult the following chapters or the dedicated manuals for details about each individual unit.
