Why Choose the ABB 1SDA125995R1 E4.3V/MS 2500 Switch-Disconnector?
The ABB 1SDA125995R1 is a high-performance SACE Emax 3 switch-disconnector moving part designed for high-current low-voltage electrical distribution systems. Configured as an E4.3V/MS 2500 three-pole withdrawable unit, it provides a rated uninterrupted current of 2500 A for dependable circuit switching and isolation.
Unlike an Emax 3 circuit breaker equipped with an Ekip electronic protection release, the E4.3V/MS is a switch-disconnector. It is intended primarily for switching and isolation duties within suitably protected electrical systems, making it appropriate for applications where a high-current disconnecting device is required as part of the overall switchgear protection architecture.
The withdrawable moving-part configuration supports convenient isolation, inspection and maintenance when used with the appropriate ABB Emax 3 fixed part. With three poles, a 2500 A current rating, 690 V AC rated operational voltage and compact E4.3 construction, the 1SDA125995R1 provides a robust solution for high-capacity industrial and commercial switchboards.

Reliable Switching and Isolation for High-Current Distribution
High-current low-voltage installations require dependable devices for switching and electrically isolating circuits during operation and maintenance. The ABB SACE Emax 3 E4.3V/MS platform provides switch-disconnector functionality for these applications, with the 1SDA125995R1 offering a rated uninterrupted current of 2500 A and a rated operational voltage of 690 V AC.
As a switch-disconnector rather than an overcurrent-protective circuit breaker, the E4.3V/MS 2500 is intended to operate as part of a suitably engineered protection system. Its withdrawable moving-part construction allows the switching unit to be isolated from the fixed portion of compatible switchgear, helping simplify inspection, servicing and maintenance in high-capacity electrical distribution installations.
Typical Applications
- Main low-voltage switchboards.
- Industrial power distribution systems.
- High-current circuit isolation.
- Data centres and critical power infrastructure.
- Commercial and large-building electrical distribution.
- Manufacturing and process facilities.
- Utility and infrastructure distribution systems.
- Generator and transformer distribution switchgear.
