Why Choose the ABB E2B/MS 1600 3P Fixed HR Switch-Disconnector?
The ABB E2B/MS 1600, order code 1SDA058949R1, is a SACE Emax switch-disconnector designed for dependable high-current switching and isolation in low-voltage power distribution systems. It combines a 1600 A rated uninterrupted current with three-pole construction, fixed installation and horizontal rear terminals.
As part of the ABB SACE Emax E2B/MS series, this device provides switching and isolation rather than integral electronic overcurrent protection. Its B performance level and robust Emax construction make it suitable for industrial, commercial and infrastructure switchboards where appropriate circuit protection is provided separately.
The E2B/MS 1600 3P F HR configuration is rated for operation up to 690 V AC and has a rated short-time withstand current of 42 kA. Its fixed construction and horizontal rear terminals provide a practical arrangement for permanent three-phase switchboard installations using rear busbar connections.
Key Advantages
- High-current 1600 A SACE Emax switch-disconnector.
- Three-pole configuration for three-phase power distribution systems.
- Fixed installation for permanent switchboard integration.
- Horizontal rear terminals facilitate rear busbar connections.
- Rated operational voltage up to 690 V AC.
- Robust E2 frame construction for demanding low-voltage distribution applications.

Reliable High-Current Switching and Isolation
Switch-disconnectors provide controlled switching and isolation of electrical circuits, allowing downstream equipment to be separated from the electrical supply for operation, inspection or maintenance. The ABB E2B/MS 1600 combines this function with the proven SACE Emax platform and substantial short-time current withstand capability for demanding low-voltage installations.
Its three-pole construction is suited to three-phase distribution systems, while the fixed installation and horizontal rear terminals provide a robust arrangement for permanent switchboard integration. This makes the E2B/MS 1600 well suited to main distribution and feeder applications where reliable high-current isolation is required.
Typical Applications
- Low-voltage main distribution switchboards.
- Industrial power distribution systems.
- High-current feeder switching and isolation.
- Three-phase electrical distribution systems.
- Manufacturing and process plant switchgear.
- Commercial and infrastructure electrical installations.
