Why Choose the ABB PR122/P-LSIRc E1-E6 Overcurrent Release?
The ABB PR122/P-LSIRc E1-E6, order code 1SDA058201R1, is an electronic overcurrent release for ABB SACE Emax air circuit breakers. Designed as an Emax accessory, it is suitable for the E1, E2, E3, E4 and E6 circuit-breaker frames and provides configurable electronic protection for low-voltage power distribution applications.
The PR122/P platform provides sophisticated electronic protection and monitoring capabilities for compatible SACE Emax circuit breakers. This LSIRc version incorporates long-time, short-time and instantaneous overcurrent protection together with residual-current protection, allowing the trip unit to respond to multiple types of abnormal current conditions within an appropriately configured electrical installation.
Supplied as a loose or configurable accessory, the 1SDA058201R1 is intended for integration with compatible SACE Emax equipment rather than use as a standalone circuit breaker. Its broad E1-E6 compatibility makes it a useful replacement or configuration component for supported ABB Emax air circuit-breaker installations.

Electronic Trip Units for SACE Emax Circuit Protection
Electronic overcurrent releases are a central part of modern air circuit-breaker protection systems. Rather than relying solely on fixed electromechanical characteristics, an electronic trip unit monitors current conditions and applies configured protection functions to determine when the associated circuit breaker should trip. This allows protection to be coordinated more effectively with the characteristics and requirements of the electrical distribution system.
The ABB PR122/P-LSIRc combines multiple protection functions within one electronic release. Long-time protection addresses sustained overloads, short-time and instantaneous protection respond to short-circuit conditions, while residual-current protection provides additional detection of current imbalance associated with leakage or earth-fault conditions. Correct selection, configuration and commissioning should always be based on the compatible SACE Emax breaker and the protection requirements of the installation.
Typical Applications
- Compatible ABB SACE Emax air circuit breakers.
- E1, E2, E3, E4 and E6 circuit-breaker frames.
- Main low-voltage electrical switchboards.
- Industrial power distribution systems.
- Commercial and infrastructure electrical distribution.
- Replacement or maintenance of compatible Emax electronic trip units.
- Distribution circuits requiring LSIRc electronic protection.
