Why Choose the ABB 1SDA081788R1 E4.2/MT 3200 MP 3p Earth DOWN Earthing Switch?
The ABB 1SDA081788R1 is an Emax 2 E4.2/MT 3200 earthing switch moving part designed for controlled earthing of compatible low-voltage switchgear. This specialised three-pole device has a rated continuous current of 3200 A and is configured for an earth connection from the lower terminals.
As part of the ABB SACE Emax 2 platform, the E4.2/MT is an earthing switch without making capacity, intended for use where a dedicated withdrawable device is required to earth the associated circuit during appropriate switchgear operating and maintenance procedures. Its E4.2 construction provides compatibility with the corresponding Emax 2 switchgear architecture.
The 1SDA081788R1 combines a three-pole configuration, 3200 A rated continuous current and withdrawable moving-part construction. The Earth DOWN designation identifies the version arranged for earthing from the lower terminals, distinguishing it from E4.2/MT variants configured for earthing from the upper terminals.
Key Advantages
- Genuine ABB SACE Emax 2 earthing switch for compatible switchgear systems.
- 3200 A rated continuous current for high-current low-voltage installations.

- ABB order code 1SDA081788R1.
Controlled Earthing for Emax 2 Switchgear
Earthing switches are used in electrical switchgear to establish an intentional connection between conductors and earth as part of defined isolation, servicing and maintenance procedures. The ABB E4.2/MT is a dedicated Emax 2 earthing device without making capacity and should therefore be applied according to the switchgear design and ABB operating requirements.
The 1SDA081788R1 is the 3200 A, three-pole Earth DOWN version, meaning its earthing arrangement is associated with the lower terminals. Its withdrawable moving-part construction allows it to interface with the corresponding Emax 2 fixed portion while supporting the operational flexibility expected from withdrawable low-voltage switchgear.
Typical Applications
- Earthing of compatible ABB Emax 2 switchgear circuits.
- Industrial low-voltage switchboards.
- Power distribution switchgear maintenance.
- Electrical isolation and maintenance procedures.
- High-current industrial power distribution systems.
- Withdrawable switchgear installations requiring lower-terminal earthing.
