Why Choose the ABB E4/MTP Earth Switch 4000 3P W MP Lower Terminal?
The ABB E4/MTP Earth Switch 4000 3P W MP Lower Terminal, order code 1SDA059108R1, is a high-current three-pole withdrawable earthing switch moving part from the ABB SACE Emax range. Designed around the E4 frame, it has a rated current of 4000 A and is intended for demanding low-voltage switchgear installations requiring a dedicated earthing function.
This specialised E4/MTP version is supplied as the moving part (MP) of a withdrawable arrangement and is specifically equipped with lower jaw-type contacts. This distinguishes 1SDA059108R1 from the corresponding upper-contact version and enables it to fulfil the required lower-terminal earthing arrangement within compatible ABB SACE Emax switchgear.
The E4/MTP combines a 4000 A rated operational and uninterrupted current with a 690 V AC rated operational voltage, 1000 V rated insulation voltage and 12 kV rated impulse withstand voltage. Its three-pole withdrawable construction makes it a purpose-designed solution for high-capacity switchboards where reliable earthing capability and serviceable switchgear architecture are required.

Dedicated Lower-Terminal Earthing Function
An earthing switch is used as part of an engineered switchgear safety arrangement to establish an intentional connection to earth. This can support safe maintenance procedures by providing the specified earthing function after the relevant circuit has been isolated and the installation's prescribed operating and safety procedures have been followed.
The ABB E4/MTP 1SDA059108R1 is specifically configured as a 4000 A three-pole withdrawable moving part with lower jaw-type contacts. Its dedicated lower-terminal configuration makes it suitable for compatible SACE Emax installations requiring earthing through the corresponding lower conductors rather than the upper-terminal arrangement.
Typical Applications
- High-current industrial low-voltage switchboards.
- Electrical switchgear earthing arrangements.
- 690 V AC three-phase power distribution systems.
- Lower-terminal earthing configurations.
- Withdrawable ABB SACE Emax switchgear assemblies.
- Large manufacturing and process plants.
- Utility, infrastructure and heavy industrial installations.
