Why Choose the ABB E2S/MS 1600 1SDA058872R1 Switch-Disconnector?
The ABB 1SDA058872R1 is a genuine SACE Emax E2S/MS 1600 switch-disconnector moving part designed for high-current switching and isolation in low-voltage power distribution systems. Rated at 1600 A, this four-pole device uses a withdrawable configuration for flexible integration into compatible ABB SACE Emax switchgear.
The MS designation identifies the switch-disconnector version of the Emax platform, intended for switching and isolation rather than automatic overcurrent protection by an integral trip unit. The E2S/MS performance level provides a short-time withstand current (Icw) of 65 kA for 1 s, supporting demanding distribution systems with high prospective fault currents.
This configuration is a four-pole withdrawable moving part (W/MP) designed for use with the corresponding compatible SACE Emax fixed part. Its withdrawable construction supports inspection, servicing and replacement while the four-pole arrangement enables simultaneous switching and isolation of all four conductors in suitable three-phase distribution systems.
Key Advantages
- Genuine ABB SACE Emax E2S/MS 1600 switch-disconnector moving part.
- 1600 A rated uninterrupted current for high-current distribution applications.
- Four-pole configuration for suitable three-phase and neutral switching systems.
- Withdrawable moving-part construction supports serviceable switchboard installations.
- 65 kA short-time withstand current for 1 s.
- Purpose-designed for dependable switching and circuit isolation.
- Compatible with the corresponding ABB SACE Emax withdrawable fixed part.
Key Features
- ABB SACE Emax E2S/MS 1600 switch-disconnector.
- 1600 A rated uninterrupted current (Iu) at 40 °C.
- Four-pole construction.
- 100% neutral-pole current-carrying capacity.

- Moving part (MP) for compatible SACE Emax withdrawable switchgear.
- E2 frame with S performance designation.
- 65 kA short-time withstand current (Icw) for 1 s.
- 690 V AC rated operational voltage for the E2S/MS platform.
- Designed for switching and isolation without an integral overcurrent protection release.
Withdrawable Four-Pole Switching and Isolation
A switch-disconnector provides controlled switching and isolation of an electrical circuit but does not perform the automatic overload and short-circuit protection functions associated with a circuit breaker equipped with an overcurrent release. Where an MS switch-disconnector is used, the electrical system must therefore incorporate appropriately coordinated protective devices elsewhere in the installation.
The ABB E2S/MS 1600 combines this isolation function with a four-pole withdrawable design and a high 65 kA one-second short-time withstand capability. The moving-part arrangement is particularly useful in switchboards where equipment needs to be withdrawn for maintenance or replacement, while the four-pole construction supports applications requiring switching of the neutral conductor together with the three phases.
Typical Applications
- Low-voltage main distribution switchboards.
- High-current industrial power distribution.
- Withdrawable switchgear assemblies.
- Four-pole circuit switching and isolation.
- Main and sectionalising switch applications.
- Manufacturing and process facilities.
- Commercial and infrastructure electrical distribution.
- Systems where overcurrent protection is provided by separately coordinated protective equipment.

Frequently Asked Questions
What is the ABB 1SDA058872R1?
The ABB 1SDA058872R1 is a SACE Emax E2S/MS 1600 four-pole withdrawable switch-disconnector moving part designed for high-current switching and isolation in low-voltage distribution systems.
What is the current rating of the ABB E2S/MS 1600 1SDA058872R1?
The E2S/MS 1600 has a rated uninterrupted current (Iu) of 1600 A at 40 °C.
Is the ABB 1SDA058872R1 fixed or withdrawable?
The 1SDA058872R1 is a withdrawable (W) moving part (MP) intended for use with the corresponding compatible ABB SACE Emax fixed part.
What is the short-time withstand current of the ABB E2S/MS 1600?
The E2S/MS platform has a short-time withstand current (Icw) of 65 kA for 1 s, providing substantial withstand capability for demanding low-voltage distribution systems.
Does the ABB E2S/MS 1600 provide automatic overcurrent protection?
No. The E2S/MS 1600 is a switch-disconnector intended for switching and isolation rather than automatic overcurrent protection by an integral trip unit. Appropriate overload and short-circuit protective devices must therefore be coordinated elsewhere in the electrical system.
