Reliable Circuit Protection for Power Distribution

Air circuit breakers such as the ABB SACE Emax E3S protect low-voltage electrical distribution systems against damaging overcurrents and short-circuit conditions. Their high current and breaking capacities make them particularly suitable for main distribution boards, industrial switchboards and other installations where reliable protection of substantial electrical loads is essential.

The PR122/P-LSIG electronic release provides multiple protection functions in a single trip unit. Long-time protection responds to sustained overloads, short-time and instantaneous functions protect against short-circuit currents, while ground-fault protection helps detect potentially dangerous current flowing to earth. This combination enables coordinated protection across complex industrial distribution systems.

Typical Applications

• Main low-voltage electrical distribution boards.
• Industrial switchboards and switchgear assemblies.
• Manufacturing and process plants.
• Commercial and industrial building power distribution.
• Transformer secondary protection.
• Generator and power distribution systems.
• Infrastructure and utility installations.
• High-current machinery and production facilities.
