1SDA073468R1 ABB E6.2X/MS 6300 4p FHR Switch-Disconnector

Why Choose the ABB E6.2X/MS 6300 4p FHR Switch-Disconnector?

The ABB E6.2X/MS 6300 4p FHR, order code 1SDA073468R1, is a high-performance four-pole air switch-disconnector designed for switching and isolation in very high-current low-voltage power distribution systems. As part of the ABB SACE Emax 2 E6.2 series, it combines a rated uninterrupted current of 6300 A with the high withstand capability associated with the E6.2X/MS performance level.

This E6.2X/MS configuration is supplied as a fixed four-pole device with horizontal rear terminals, providing a robust connection arrangement for integration with high-current switchboard busbars. The MS switch-disconnector configuration is intended for circuit switching and isolation duties, while the Emax 2 platform provides a proven architecture for demanding industrial and infrastructure power distribution installations.

The X performance level distinguishes this model from the E6.2H/MS version, providing a rated short-time withstand current of up to 120 kA for 1 s. Combined with its 6300 A current rating and four-pole configuration, the E6.2X/MS is particularly suited to major distribution assemblies where very high prospective fault currents must be accommodated.

Key Advantages

• Very high 6300 A rated uninterrupted current for major power distribution systems.
• Four-pole configuration for switching and isolation of three-phase systems with neutral.
• High 120 kA short-time withstand current for 1 s.

Reliable High-Current Switching and Isolation

Air switch-disconnectors provide a dependable means of switching and electrically isolating sections of a low-voltage installation. The ABB E6.2X/MS combines very high continuous-current capability with substantial short-time withstand performance, helping power distribution assemblies accommodate demanding electrical conditions while providing a dedicated isolation function.

The Emax 2 E6.2 platform is designed for high-capacity low-voltage distribution systems. With its 6300 A uninterrupted current rating and 120 kA for 1 s short-time withstand capability, the E6.2X/MS configuration is particularly suited to main distribution and isolation duties where high prospective short-circuit currents and robust electrical performance are key design requirements.

Typical Applications

• High-capacity low-voltage main distribution switchboards.
• Industrial power distribution systems.
• Large commercial and infrastructure electrical installations.
• Main incoming and distribution isolation duties.
• Manufacturing and heavy-industry electrical systems.
• Power distribution assemblies requiring high-current four-pole isolation.
