Why Choose the ABB E3S/MS 1600 3P Fixed HR Switch-Disconnector?
The ABB E3S/MS 1600, order code 1SDA058969R1, 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 E3S/MS series, this device provides switching and isolation rather than integral electronic overcurrent protection. Its E3 frame and S short-circuit performance level make it suitable for demanding industrial, commercial and infrastructure switchboards where suitable circuit protection is coordinated separately.
The E3S/MS 1600 3P F HR configuration is rated for operation at up to 690 V AC and provides a rated short-time withstand current of 75 kA for 1 s. Its fixed construction and horizontal rear terminals provide a robust arrangement for permanent switchboard installations with 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 of 690 V AC / 250 V DC.
- High 75 kA short-time withstand current for 1 s.
Key Features
- ABB SACE Emax E3S/MS series.
- 1600 A rated uninterrupted current.
- Three-pole (3P) construction.
- Fixed (F) execution.
- Rear flat horizontal (HR) terminals.
- S short-circuit performance level.

- 1000 V rated insulation voltage.
- 12 kV rated impulse withstand voltage.
- IP30 frontal protection.
High-Current Switching and Isolation for Power Distribution
The ABB E3S/MS 1600 provides controlled switching and isolation of high-current electrical circuits, allowing downstream equipment to be disconnected from the supply for operation, inspection or maintenance. As an MS switch-disconnector execution, it is intended for switching and isolation, with appropriate overcurrent and short-circuit protection provided elsewhere in the electrical installation.
Its three-pole construction is suited to three-phase distribution systems, while the fixed configuration provides a robust permanent installation. Rear flat horizontal terminals facilitate connection to switchboard busbars, making the E3S/MS 1600 particularly suitable for demanding high-current distribution assemblies.
Typical Applications
- Low-voltage main distribution switchboards.
- Industrial three-phase power distribution systems.
- High-current feeder switching and isolation.
- Manufacturing and process plant switchgear.
- Commercial building electrical distribution.
- Infrastructure and utility power installations.
