Why Choose the ABB E1B 1000 PR121/P-LI In=1000A 4p F H Air Circuit Breaker?
The ABB E1B 1000 PR121/P-LI In=1000A 4p F H, order code 1SDA059171R1, is a four-pole fixed SACE Emax air circuit breaker designed for low-voltage power distribution applications. It combines the compact E1 frame with a 1000 A rated current configuration and ABB's PR121/P-LI electronic trip unit.
The PR121/P-LI release provides long-time overload protection (L) and instantaneous short-circuit protection (I). This LI protection configuration is suited to installations requiring dependable overload and instantaneous short-circuit protection without the additional short-time or earth-fault functions associated with LSI and LSIG trip-unit configurations.
The E1B1000PR121/P-LIIn=1000A4pFH combines a four-pole arrangement with a fixed installation format and horizontal rear terminals. ABB order code 1SDA059171R1 provides precise identification for specification, procurement and replacement within compatible SACE Emax power distribution systems.

Reliable Circuit Protection, Switching and Isolation
Air circuit breakers are used in low-voltage power distribution systems to switch circuits and provide automatic protection against abnormal overcurrent conditions. An electronic trip unit monitors current and commands the circuit breaker to open when the applicable protection threshold and operating characteristic are reached.
The ABB 1SDA059171R1 combines a 1000 A E1B circuit breaker with the PR121/P-LI electronic trip unit, providing long-time overload and instantaneous short-circuit protection. Its four-pole fixed construction and horizontal rear terminal arrangement make it suitable for correctly designed SACE Emax switchboards requiring this specific configuration.
Typical Applications
- Industrial low-voltage power distribution systems.
- Main and sub-main electrical distribution switchboards.
- 1000 A three-phase and neutral distribution circuits.
- Four-pole switching and circuit protection applications.
- Commercial and industrial electrical installations.
- Manufacturing and process plant distribution systems.
- OEM switchboards requiring fixed SACE Emax circuit breakers with LI protection.
