Reliable Circuit Protection for Power Distribution

Air circuit breakers such as the ABB SACE Emax E1B are designed to protect low-voltage electrical distribution systems against potentially damaging overcurrent conditions. The electronic trip unit continuously monitors current and initiates circuit breaker operation when configured protection thresholds are exceeded.

The PR122/P-LI release provides electronic long-time and instantaneous protection, helping protect cables, busbars and connected equipment against overload and short-circuit conditions. The withdrawable construction allows the circuit breaker moving part to be removed from its switchboard cradle, supporting inspection, maintenance and replacement while providing the flexibility required in industrial distribution systems.

Typical Applications

• Industrial low-voltage switchboards.
• Main and distribution power circuits.
• Manufacturing and process facilities.
• Commercial and industrial power distribution.
• Electrical distribution panels and assemblies.
• Infrastructure and utility installations.
• Systems requiring withdrawable circuit breaker arrangements.
