Reliable Circuit Protection for Power Distribution

Air circuit breakers such as the ABB SACE Emax E1B protect low-voltage electrical distribution systems against damaging overcurrent conditions. The electronic trip unit monitors circuit current and initiates breaker operation when configured protection thresholds are exceeded, helping protect cables, busbars, switchgear and connected equipment.

The PR122/P-LSI release provides long-time, short-time and instantaneous protection functions, allowing the circuit breaker to respond appropriately to overload and short-circuit conditions. Its fixed construction and rear horizontal terminals make the 1SDA059185R1 particularly suitable for permanent installation within industrial and commercial low-voltage switchboards.
