1SDA059109R1 ABB E4MTP Earth Switch Up-Term 4000 A 4-Pole Withdrawable Moving Part

Why Choose the ABB E4MTP Earth Switch Up-Term 4000 4P?

The ABB E4MTP Earth Switch Up-Term 4000 4P, order code 1SDA059109R1, is a specialised SACE Emax E4/MTP earthing switch moving part designed for controlled earthing duties in compatible low-voltage switchgear. This heavy-duty version combines a 4000 A rated current, four-pole configuration and withdrawable construction for demanding industrial power distribution assemblies.

ABB's MTP configuration is an earthing switch with making capacity derived from the SACE Emax platform. Rather than providing conventional automatic circuit-breaker protection, it performs a dedicated earthing function within an appropriately engineered switchboard, supporting controlled isolation and maintenance procedures.

This particular model is the upper-terminal version and is designed for the corresponding E4/MTP arrangement. Its four-pole construction and substantial 4000 A current capability make it suitable for large switchgear installations where a dedicated high-current earthing solution is required.

Key Advantages

• Purpose-designed SACE Emax earthing switch with making capacity.
• 4000 A rated current for very high-current switchgear applications.
• Four-pole configuration for compatible four-conductor power systems.
• Upper-terminal arrangement for the specified E4/MTP assembly.
• Withdrawable moving-part construction supports servicing and switchboard flexibility.
• Robust E4-frame architecture for demanding industrial earthing duties.

Dedicated High-Current Upper-Terminal Earthing

Earthing switches form part of engineered switchgear systems used to establish an intentional connection to earth after the relevant electrical circuit has been isolated and verified. This dedicated function supports controlled maintenance procedures and safe management of de-energised conductors in accordance with the installation's operating and safety requirements.

ABB 1SDA059109R1 is specifically configured as a 4000 A four-pole E4/MTP upper-terminal moving part. Its withdrawable SACE Emax architecture provides a serviceable solution for compatible high-current switchboards while retaining the dedicated making-capacity earthing function required by the MTP arrangement.

Typical Applications

• High-current industrial switchgear assemblies.
• SACE Emax E4/MTP earthing arrangements.
• Four-pole power distribution switchboards.
• Industrial electrical isolation and maintenance systems.
• High-current upper-terminal earthing arrangements.
• Manufacturing, infrastructure and process-industry power distribution.
