Reliable Circuit Protection for Electrical Distribution Systems
Moulded case circuit breakers such as the ABB EPX-XT2S-E2-0253 protect electrical circuits against excessive current caused by overloads and short circuits. When an electrical fault occurs, the breaker interrupts the affected circuit to help prevent damage to cables, distribution equipment and connected electrical installations.
The electronic LSI trip unit provides three essential protection functions. Long-time protection responds to sustained overload conditions, short-time protection enables delayed operation during short-circuit events, and instantaneous protection provides rapid interruption of severe faults. These functions help electrical engineers coordinate protective devices and improve the reliability of low-voltage distribution systems.
As part of the ABB Protecta Power Devices range, the EPX-XT2S-E2-0253 is designed for electrical installations where reliable fault interruption, coordinated protection and compact distribution equipment are important.
