1SDA059096R1 ABB E1MTP Earth Switch Low-Term 1250 A 3-Pole Withdrawable Moving Part

Why Choose the ABB E1MTP Earth Switch Low-Term 1250 3P?

The ABB E1MTP Earth Switch Low-Term 1250 3P, order code 1SDA059096R1, is a specialised SACE Emax earthing switch moving part designed for controlled earthing duties in compatible low-voltage switchgear. This E1/MTP version is rated at 1250 A and uses a three-pole withdrawable configuration.

ABB identifies this device as a derived-version earthing switch with making capacity MTP. Rather than functioning as a conventional circuit breaker, it provides a dedicated earthing function within an appropriately engineered switchboard installation, supporting controlled isolation and maintenance procedures.

This particular version features lower jaw-type contacts and a withdrawable moving-part design. Its E1 frame construction and SACE Emax architecture make it suitable for integration with the corresponding compatible E1/MTP switchgear arrangement where lower-terminal earthing is required.

Key Advantages

• Purpose-designed SACE Emax earthing switch with making capacity.
• 1250 A rated current for substantial low-voltage distribution systems.
• Three-pole configuration for compatible three-phase switchgear applications.
• Lower jaw-type contacts for the specified E1/MTP lower-terminal arrangement.
• Withdrawable moving-part construction supports integration and servicing within compatible assemblies.
• Dedicated earthing functionality for appropriately controlled isolation and maintenance procedures.

Key Features

Dedicated Lower-Terminal Earthing Function

Earthing switches are used as part of engineered switchgear arrangements to establish an intentional connection to earth. In appropriately designed installations, this provides a dedicated earthing function after the associated electrical circuit has been isolated and verified in accordance with the site's electrical safety procedures.

ABB 1SDA059096R1 is specifically configured as the 1250 A three-pole E1/MTP moving part with lower jaw-type contacts. The withdrawable architecture enables integration with the corresponding SACE Emax assembly while providing the lower-terminal contact arrangement required by this particular MTP configuration.

Typical Applications

• Low-voltage industrial switchgear assemblies.
• SACE Emax E1/MTP earthing arrangements.
• Three-phase distribution switchboards.
• Industrial electrical isolation systems.
• Lower-terminal maintenance earthing arrangements.
• Manufacturing, infrastructure and process-industry power distribution.
