Why Choose the ABB E3S/MS 1250 4P Fixed HR Switch-Disconnector?
The ABB E3S/MS 1250, order code 1SDA058968R1, is a SACE Emax switch-disconnector designed for dependable high-current switching and isolation in low-voltage power distribution systems. It combines a 1250 A rated current with four-pole construction, fixed installation and horizontal rear terminals.
As part of the ABB SACE Emax E3S/MS series, this device is intended for switching and isolation rather than integral electronic overcurrent protection. Its E3 frame and S performance level provide a robust solution for demanding industrial, commercial and infrastructure switchboards where suitable circuit protection is provided separately.
The E3S/MS 1250 4P F HR configuration provides four poles for applications requiring simultaneous switching of three phases and neutral. Its fixed construction and horizontal rear (HR) terminals make it particularly suitable for permanent switchboard installations with rear busbar connections.

High-Current Switching and Isolation for Power Distribution
The ABB E3S/MS 1250 provides controlled switching and isolation of high-current electrical circuits, allowing downstream equipment to be disconnected from the supply when required for operation or maintenance. As an MS switch-disconnector execution, it is intended for switching and isolation, with appropriate overcurrent and short-circuit protection coordinated elsewhere in the electrical installation.
Its four-pole construction supports systems requiring switching of three phases and neutral, while the fixed design provides a robust permanent installation. Horizontal rear terminals facilitate connection to switchboard busbars, making the unit well suited to high-current distribution assemblies.
Typical Applications
- Low-voltage main distribution switchboards.
- Industrial power distribution systems.
- High-current feeder switching and isolation.
- Four-pole three-phase and neutral distribution systems.
- Manufacturing and process plant switchgear.
- Commercial and infrastructure electrical installations.
