1SDA074379R1 ABB Grounding Clamp FP E4.2–E6.2 for MT/MTP

Why Choose the ABB 1SDA074379R1 Grounding Clamp FP E4.2–E6.2?

The ABB 1SDA074379R1 is a grounding clamp for the fixed part (FP) of compatible ABB SACE Emax 2 E4.2 and E6.2 withdrawable switchgear installations using MT or MTP devices. This genuine ABB accessory provides the grounding interface required when an MT earthing truck or MTP earthing switch with making capacity is used with the corresponding fixed part.

Designed for E4.2 and E6.2 Emax 2 frame sizes, the 1SDA074379R1 forms part of ABB's dedicated accessory range for MT and MTP configurations. The grounding clamp is installed in the fixed part so that the compatible MT/MTP mobile part can be accepted and correctly integrated into the withdrawable switchgear arrangement.

ABB specifies that grounding clamps must be installed in every fixed part where an MT or MTP mobile part is foreseen. Standard fixed parts without the required grounding clamps cannot accept the MT/MTP device, making the 1SDA074379R1 an important configuration component for compatible E4.2 and E6.2 installations.

Key Advantages

• ABB order code 1SDA074379R1.

Grounding Interface for Emax 2 MT and MTP Systems

ABB's Emax 2 MT and MTP devices are specialised withdrawable configurations used for earthing functions within compatible switchgear. The MT range comprises earthing trucks, while MTP identifies earthing switches with making capacity. Their use requires the corresponding fixed part to be equipped with the appropriate grounding-clamp arrangement.

The ABB 1SDA074379R1 provides this grounding-clamp functionality for E4.2 and E6.2 fixed parts. ABB specifies that the clamp must be installed in fixed parts intended to receive an MT or MTP mobile part; without the appropriate grounding clamp, a standard fixed part cannot accept the MT/MTP device.

Typical Applications

• ABB SACE Emax 2 E4.2 fixed parts.
• ABB SACE Emax 2 E6.2 fixed parts.
• Switchgear installations using compatible MT earthing trucks.
• Switchgear installations using compatible MTP earthing switches with making capacity.
• Industrial low-voltage withdrawable switchboards.
• New Emax 2 switchgear assemblies configured to accept MT/MTP mobile parts.
