Why Choose the ABB 1SDA059426R1 E3S/MS1000 Switch-Disconnector?
The ABB 1SDA059426R1 is a SACE Emax E3S/MS air switch-disconnector moving part designed for switching and isolation duties in demanding low-voltage electrical distribution systems. Identified by ABB as E3S/MS10003pWMPnew, this three-pole withdrawable unit has a rated current of 1000 A and is intended for use with a compatible SACE Emax withdrawable fixed part.
Unlike an E3S circuit breaker equipped with a PR electronic trip unit, the E3S/MS is a switch-disconnector and does not provide automatic overload or short-circuit protection. Its primary purpose is dependable load switching and circuit isolation, with system overcurrent protection provided by appropriately coordinated upstream or external protective devices.
The 1SDA059426R1 combines a 690 V AC rated operational voltage, 1000 V insulation voltage and high short-time withstand capability with a withdrawable construction that simplifies isolation and servicing. This makes it particularly suitable for industrial and commercial switchboards where maintainability, positive circuit isolation and high-current switching are important.
Key Advantages
- 1000 A rated current for high-current low-voltage distribution systems.
- Three-pole configuration for three-phase switching and isolation.
- Withdrawable moving-part design supports convenient isolation and switchboard maintenance.
- Dedicated switch-disconnector construction for switching and isolation duties.
- 690 V AC rated operational voltage for demanding industrial distribution applications.
- 75 kA short-time withstand current for 1 s.
- 65 kA short-time withstand current for 3 s.
- ABB SACE Emax construction for integration into compatible withdrawable switchgear assemblies.

Reliable Switching and Isolation for Power Distribution
The ABB SACE Emax E3S/MS is designed for applications where high-current circuits need to be switched and positively isolated without incorporating an automatic overcurrent protection release. As a switch-disconnector, it performs a different role from an E3S air circuit breaker fitted with a PR121/P, PR122/P or PR123/P trip unit.
The withdrawable construction of the 1SDA059426R1 allows the moving part to be disconnected from its compatible fixed part, supporting maintenance and operational isolation procedures. Because the E3S/MS does not provide automatic overload or short-circuit tripping, suitable external or upstream protective devices must be incorporated into the electrical system design.
Typical Applications
- Main low-voltage electrical distribution switchboards.
- Industrial power distribution systems.
- Commercial building electrical infrastructure.
- High-current circuit switching and isolation.
- Manufacturing and process plant switchboards.
- Transformer secondary distribution systems.
- Generator and standby power distribution systems.
- Withdrawable switchgear requiring a dedicated 1000 A switch-disconnector.
