Why Choose the ABB E1B 800 PR122/P-LI 800A Air Circuit Breaker?
The ABB E1B 800 PR122/P-LI, order code 1SDA055619R1, is a high-performance 800 A three-pole air circuit breaker moving part designed for protection and switching in low-voltage electrical distribution systems. As part of the established ABB SACE Emax series, it combines robust circuit-breaking performance with the advanced PR122/P-LI electronic overcurrent release for dependable protection of industrial power networks.
This E1B circuit breaker is supplied in a withdrawable moving-part configuration, allowing the breaker to be disconnected and removed from its compatible fixed part for inspection, servicing or replacement. The PR122/P-LI electronic trip unit provides long-time and instantaneous protection functions, helping protect electrical installations against sustained overloads and high-level short circuits.
With a rated uninterrupted current of 800 A, three-pole construction and a rated ultimate short-circuit breaking capacity of 42 kA at 400 V AC, the E1B 800 is engineered for demanding industrial distribution applications. It is also equipped with four auxiliary circuit-breaker contacts for open/closed position signalling and integration with control and monitoring systems.

Reliable Protection for Low-Voltage Distribution Systems
Air circuit breakers such as the ABB SACE Emax E1B protect high-current electrical distribution systems by interrupting abnormal current conditions before cables, switchgear and connected equipment can be damaged. Their high breaking capacity makes them particularly suitable for main distribution boards and industrial power systems where substantial prospective fault currents may occur.
The PR122/P-LI electronic release combines long-time overload protection with instantaneous short-circuit protection, allowing the breaker to respond to both sustained overcurrent conditions and severe faults. The withdrawable construction also supports efficient servicing and replacement within compatible SACE Emax switchgear assemblies without requiring the complete installation to be dismantled.
Typical Applications
- Industrial low-voltage distribution switchboards.
- Main incoming and distribution circuit protection.
- Manufacturing plants and production facilities.
- Commercial and infrastructure electrical distribution systems.
- Motor control centres and industrial power systems.
- Generator and transformer distribution installations.
- Power distribution panels requiring withdrawable circuit breakers.
