Information About PR122/P-LSIG
The PR122/P-LSIG belongs to ABB's SACE Emax electronic trip-unit family and is designed for compatible three-pole and four-pole air circuit breakers. Its LSIG protection functions include long-time overload, short-time short-circuit, instantaneous short-circuit, and ground-fault protection. Adjustable trip thresholds and time delays allow protection settings to be coordinated with the electrical installation. Depending on the configuration, additional modules can provide communication, voltage measurement, and expanded monitoring functions.
Key Features:
-
Electronic Trip Technology: Microprocessor-based protection for compatible ABB Emax circuit breakers.
-
LSIG Protection: Combines long-time, short-time, instantaneous, and ground-fault protection.
-
Adjustable Overload Protection: Configurable long-time current thresholds and delay settings.
-
Short-Circuit Protection: Provides adjustable short-time and instantaneous trip functions.
-
Ground-Fault Protection: Supports adjustable earth-fault protection.
-
Selective Coordination: Supports coordination between upstream and downstream breakers.
-
Measurement and Monitoring: Provides operating information through the trip unit's user interface.
-
Optional Expansion Modules: Compatible configurations can support additional measurement and communication functions.
The PR122/P-LSIG delivers configurable electronic protection and monitoring capabilities for compatible ABB SACE Emax power distribution systems.
