Why Choose the ABB E3L2000 PR121/P-LSIG 2000A 4P Withdrawable Air Circuit Breaker?
The ABB E3L2000 PR121/P-LSIG, order code 1SDA056746R1, is a high-performance SACE Emax E3L air circuit breaker moving part designed for protection and switching in high-current low-voltage electrical distribution systems. Rated at 2000 A, this four-pole withdrawable configuration combines the proven ABB SACE Emax platform with a PR121/P-LSIG R2000 electronic overcurrent release.
The PR121/P-LSIG release provides long-time (L), short-time (S), instantaneous (I) and earth-fault (G) protection, providing comprehensive protection against overload, short-circuit and earth-fault conditions. This combination makes the E3L2000 particularly suitable for main distribution switchboards and critical industrial power systems where selective protection and convenient circuit-breaker maintenance are important.
This version is supplied as the four-pole withdrawable moving part (W MP) of the E3L2000 circuit breaker and is designed for use with the appropriate SACE Emax fixed part. The withdrawable arrangement enables the breaker moving part to be disconnected and removed from its fixed section, supporting inspection, maintenance and replacement while retaining the switchboard installation.
Key Advantages
- High-current 2000 A SACE Emax E3L circuit breaker moving part for low-voltage power distribution.
- Four-pole configuration for switching and protection across four conductors.
- PR121/P-LSIG electronic overcurrent release provides comprehensive L, S, I and G protection functions.

Comprehensive Protection for High-Current Electrical Distribution
Air circuit breakers such as the ABB SACE Emax E3L are designed to protect high-capacity low-voltage distribution systems against abnormal current conditions. The PR121/P-LSIG electronic release combines overload, short-time, instantaneous and earth-fault protection functions, allowing coordinated protection of feeders, busbars and connected electrical equipment.
The withdrawable E3L2000 configuration is particularly useful in switchboards where serviceability and operational flexibility are important. The moving circuit-breaker section can be withdrawn from its corresponding fixed part for inspection or maintenance, while the four-pole configuration and 2000 A current rating make this model suitable for substantial industrial and commercial distribution loads.
Typical Applications
- Main low-voltage electrical distribution switchboards.
- Industrial power distribution systems.
- High-current incoming and feeder protection.
- Commercial and infrastructure electrical distribution.
- Manufacturing and process-industry switchgear.
- Transformer and generator distribution systems.
- Switchboards requiring withdrawable circuit breakers for improved serviceability.
- Electrical installations requiring four-pole protection including earth-fault protection.
