Why Choose the ABB 1SDA059425R1 E3S/MS 1000 Switch Disconnector?
The ABB 1SDA059425R1 is a SACE Emax E3S/MS 1000 switch disconnector designed for high-current switching and isolation in low-voltage power distribution systems. Configured as E3S/MS 1000 3p F HR, it combines a 1000 A rated current, three-pole construction, fixed execution and horizontal rear terminals.
Unlike an automatic circuit breaker fitted with a protective trip unit, the E3S/MS is a switch-disconnector intended primarily for switching and isolation duties. Its E3S performance level and robust SACE Emax construction make it suitable for industrial and commercial switchboards requiring dependable high-current circuit isolation.
The 1SDA059425R1 is rated for operation up to 690 V AC and provides a rated short-time withstand current of 75 kA for 1 s and 65 kA for 3 s. Its fixed construction with horizontal rear terminals supports permanent switchboard installation and practical rear busbar or conductor connections.
Key Advantages
- 1000 A switch disconnector for high-current low-voltage distribution systems.
- Three-pole configuration suitable for three-phase switching and isolation.
- Fixed execution for permanent switchboard installation.
- Horizontal rear terminals for practical rear connections.
- 690 V AC rated operational voltage.
- 75 kA short-time withstand current for 1 s.

Reliable Switching and Isolation for Low-Voltage Distribution
The ABB SACE Emax E3S/MS is designed for applications requiring dependable switching and isolation of high-current low-voltage circuits. With a rated current of 1000 A and short-time withstand capability of 75 kA for 1 s, the 1SDA059425R1 is suited to demanding distribution systems where robust isolation performance is required.
Its fixed three-pole construction and horizontal rear terminals make the switch disconnector suitable for permanent integration into industrial and commercial switchboards. As an MS switch-disconnector configuration, it provides switching and isolation functionality rather than the automatic overcurrent protection functions associated with SACE Emax circuit breakers equipped with PR electronic trip units.
Typical Applications
- Low-voltage main distribution switchboards.
- Industrial power distribution systems.
- Commercial building electrical distribution.
- Manufacturing and process plant switchgear.
- High-current feeder isolation.
- Three-phase circuit switching and isolation.
- Fixed switchgear and distribution assemblies.
- Applications requiring a 1000 A switch disconnector without an automatic protection trip unit.
