Why Choose the ABB 1SDA060721R1 E2N-A 800 Air Circuit Breaker?
The ABB 1SDA060721R1, manufacturer designation E2N-A 800 PR123/P-LSIG In=800A 3p W, is a SACE Emax E2N-A moving part for a withdrawable air circuit breaker designed for protection, switching and control in demanding low-voltage power distribution systems. This three-pole unit combines an 800 A rated current with ABB's advanced PR123/P-LSIG electronic overcurrent release for comprehensive electrical protection.
The PR123/P electronic trip unit provides LSIG protection functions, covering long-time overload, short-time selective short-circuit, instantaneous short-circuit and earth-fault protection. These functions make the breaker suitable for industrial and commercial distribution systems where advanced electronic protection, selective fault isolation and dependable circuit control are required.
The 1SDA060721R1 is a three-pole withdrawable E2N-A 800 breaker moving part with an 800 A rated current. Its withdrawable configuration allows the breaker moving portion to be disconnected and removed from a compatible fixed part, supporting inspection, maintenance and replacement in switchboards where serviceability is an important requirement.

Advanced Electronic Protection for Power Distribution
The ABB PR123/P electronic release provides advanced protection functionality for low-voltage electrical networks. Its LSIG configuration combines long-time overload protection, short-time selective protection, instantaneous short-circuit protection and earth-fault protection, enabling the circuit breaker to respond appropriately to a range of abnormal operating and fault conditions.
As the moving part of a withdrawable SACE Emax installation, the 1SDA060721R1 can be used with the appropriate compatible fixed part to create a serviceable circuit-breaker system. This arrangement is particularly valuable in critical switchboards because the breaker can be isolated and withdrawn for inspection or maintenance while the fixed portion remains installed.
Typical Applications
- Industrial low-voltage switchboards.
- Main electrical distribution panels.
- Commercial building power distribution.
- Manufacturing and process facilities.
- Power protection and control systems.
- Withdrawable ABB SACE Emax circuit-breaker installations.
