Why Choose the ABB E1B 1000 PR122/P-LI 1000A 3P Withdrawable Circuit Breaker?
The ABB E1B 1000 PR122/P-LI, order code 1SDA059182R1, is a SACE Emax air circuit breaker engineered for high-current low-voltage power distribution. Rated at 1000 A, this E1-frame breaker combines a three-pole configuration with ABB's PR122/P-LI electronic trip unit for long-time and instantaneous overcurrent protection.
This model is supplied in a withdrawable configuration as the moving part (W MP), making it suitable for compatible switchgear assemblies where the breaker can be disconnected from the fixed portion without removing the main switchboard connections. This arrangement supports maintainability, inspection and replacement within suitably designed power distribution systems.
The combination of the E1B frame, 1000 A rated current and PR122/P-LI protection provides a dependable solution for main and feeder circuit protection. Its electronic trip unit provides LI protection functions, covering overload protection through the long-time function and high-current short-circuit protection through the instantaneous function.

Electronic Protection for High-Current Power Distribution
The PR122/P-LI electronic trip unit provides two fundamental overcurrent protection functions. Long-time protection responds to sustained overload conditions that could otherwise cause excessive heating in cables and distribution equipment, while instantaneous protection responds rapidly to high-magnitude short-circuit currents without an intentional time delay.
Combined with the E1B air circuit breaker platform, these protection functions make the ABB 1SDA059182R1 suitable for applications requiring dependable 1000 A circuit protection. Its withdrawable moving-part construction also supports switchgear architectures designed for inspection, maintenance and replacement while retaining the corresponding fixed portion within the switchboard.
Typical Applications
