Why Choose the ABB PR122/P-LSI E1-E6 Overcurrent Release?
The ABB 1SDA058197R1 is a PR122/P-LSI electronic overcurrent release designed for use with ABB SACE Emax air circuit breakers. Part of the ABB New Emax accessory range, this configurable protection unit is suitable for E1, E2, E3, E4 and E6 circuit breaker frames and provides advanced electronic protection for low-voltage power distribution systems.
The PR122/P-LSI provides Long-time, Short-time and Instantaneous protection functions, identified by the LSI designation. These functions allow the trip unit to respond to sustained overloads, controlled short-circuit conditions and severe instantaneous faults, supporting effective protection and coordination within industrial and commercial electrical distribution networks.
ABB order code 1SDA058197R1 identifies the loose or configurable PR122/P-LSI overcurrent release for the SACE Emax E1-E6 platform. Its modular design allows the appropriate rating plug to be selected according to the compatible Emax breaker frame and required rated current, making the unit suitable for a broad range of Emax circuit breaker applications.

Advanced Electronic Protection for SACE Emax Circuit Breakers
Electronic overcurrent releases such as the ABB PR122/P monitor current conditions through the associated circuit breaker and initiate tripping when configured protection thresholds are exceeded. This provides dependable protection for conductors, busbars, switchgear and connected electrical equipment while allowing protection characteristics to be coordinated throughout a low-voltage distribution system.
The PR122/P-LSI combines Long-time protection for sustained overloads, Short-time protection for selective short-circuit coordination and Instantaneous protection for severe faults requiring rapid interruption. Compatible rating plugs allow the release to be matched to supported Emax breaker frame sizes and current ratings, providing flexibility for maintenance, replacement and system configuration.
Typical Applications
- ABB SACE Emax E1-E6 air circuit breaker protection.
- Replacement or configurable trip unit applications.
- Main incoming circuit breakers in low-voltage switchboards.
- Industrial power distribution and protection systems.
- Feeder and bus-section circuit breaker protection.
- Commercial, infrastructure and manufacturing electrical installations.
