Why Choose the ABB E1.2N/MS 1600 3p F F Switch-Disconnector?
The ABB E1.2N/MS 1600 3p F F, order code 1SDA073401R1, is a 1600 A three-pole fixed switch-disconnector from the ABB SACE Emax 2 range, designed for reliable isolation and switching in demanding low-voltage power distribution systems.
Unlike an Emax 2 circuit breaker fitted with an Ekip protection trip unit, the E1.2N/MS is a switch-disconnector configuration intended primarily for switching and isolation rather than automatic overcurrent protection. This makes it suitable for installations where circuit protection is provided by separate upstream or downstream protective devices.
The unit features a compact E1.2 frame, 1600 A rated uninterrupted current, three-pole construction and a fixed installation arrangement with front terminals. Its N performance configuration provides a rated short-time withstand current of 50 kA for 1 s, supporting dependable operation in high-current distribution assemblies.
Key Advantages
- High-capacity 1600 A switch-disconnector for low-voltage power distribution.
- Provides dependable switching and circuit isolation.
- Three-pole configuration for three-phase AC systems.
- Compact ABB SACE Emax 2 E1.2 frame.
- 50 kA short-time withstand current for 1 s.
- 36 kA short-time withstand current for 3 s.
- Fixed construction simplifies permanent switchboard installation.
- Front terminals provide a practical main-circuit connection arrangement.
Key Features
- ABB SACE Emax 2 E1.2N/MS series.
- 1600 A rated uninterrupted current.
- Three-pole configuration.
- Switch-disconnector functionality without an integrated protection trip unit.
- 690 V AC rated operational voltage.
- 50 kA Icw for 1 s.
- 36 kA Icw for 3 s.
- Fixed mounting arrangement.
- Front main-circuit terminals.
- Compact 210 × 296 × 183 mm dimensions.
- Approximately 14 kg net weight.
Reliable High-Current Switching and Isolation
The ABB SACE Emax 2 E1.2N/MS platform provides switch-disconnector functionality in the same compact architecture used throughout the Emax 2 family. Its 1600 A current rating and substantial short-time withstand capability make it suitable for high-current switchboards where dependable isolation and switching are required.
Because this MS configuration is a switch-disconnector rather than an automatically tripping protective circuit breaker, overcurrent and fault protection should be provided by suitable external protective devices within the electrical system. The fixed construction and front terminals make the unit particularly appropriate for permanent switchboard installations.
Typical Applications
- Low-voltage main distribution switchboards.
- High-current circuit isolation and switching.
- Industrial power distribution systems.
- Commercial and infrastructure electrical installations.
- Switchboards using separate overcurrent protection devices.
- Power distribution systems requiring fixed front-connected switching devices.
