Why Choose the ABB PR121/P-LSIG E1-E6 Overcurrent Release?
The ABB PR121/P-LSIG E1-E6, order code 1SDA058195R1, is an electronic overcurrent release for ABB SACE Emax air circuit breakers. Designed as an Emax accessory and replacement trip unit, it is suitable for the E1, E2, E3, E4 and E6 breaker frames and provides comprehensive electronic protection for low-voltage power distribution applications.
The PR121/P-LSIG configuration provides four key protection functions: long-time overload protection (L), short-time short-circuit protection (S), instantaneous short-circuit protection (I) and ground-fault protection (G). This combination enables the trip unit to protect electrical distribution systems against a broad range of overcurrent and ground-fault conditions when correctly configured for the associated SACE Emax circuit breaker.
ABB identifies 1SDA058195R1 as a loose or configurable Emax accessory manufactured to IEC requirements. The unit has a net weight of approximately 1 kg and is supplied as a standalone overcurrent release, allowing the appropriate rating plug and breaker-specific settings to be selected for the intended Emax installation.
Key Advantages
- LSIG electronic protection covering overload, short-time, instantaneous and ground-fault conditions.
- Suitable for multiple ABB SACE Emax frame sizes from E1 through E6.
- Designed specifically as an overcurrent release for Emax air circuit breakers.
- Loose or configurable format supports replacement and breaker-specific configuration.
- Electronic protection supports accurate and repeatable circuit-breaker tripping characteristics.
- ABB-engineered accessory for maintaining compatible SACE Emax protection systems.
Key Features
- ABB PR121/P electronic trip-unit platform.
- LSIG protection functions.
- Long-time overload protection (L).
- Short-time short-circuit protection (S).
- Instantaneous short-circuit protection (I).
- Ground-fault protection (G).
- Compatible with SACE Emax E1, E2, E3, E4 and E6.
- Designed as a loose/configurable Emax accessory.
Reliable Protection for High-Current Power Distribution
The PR121/P family forms part of the electronic protection system used with ABB SACE Emax air circuit breakers. Rather than being a complete circuit breaker itself, the 1SDA058195R1 is the electronic overcurrent release that supervises electrical conditions and commands the associated breaker to trip when configured protection thresholds are exceeded.
With LSIG functionality, the PR121/P-LSIG provides a broad protection package for distribution systems requiring overload, selective short-time, rapid instantaneous and ground-fault protection. Actual current ratings and protection settings depend on the compatible Emax breaker, rating plug and application configuration with which the release is used.
Typical Applications
- Replacement overcurrent release for compatible ABB SACE Emax breakers.
- Main low-voltage distribution switchboards.
- Industrial power distribution systems.
- Commercial and infrastructure switchgear.
- Transformer and generator distribution systems.
- Applications requiring LSIG electronic circuit protection.
- Maintenance and refurbishment of compatible Emax E1-E6 circuit breakers.
