1SDA073463R1 ABB E6.2H/MS 4000 4p F HR Switch-Disconnector

Why Choose the ABB E6.2H/MS 4000 4p F HR Switch-Disconnector?

The ABB E6.2H/MS 4000 4p F HR, order code 1SDA073463R1, is a high-capacity four-pole fixed air switch-disconnector from the ABB SACE Emax 2 range. Rated at 4000 A, it is engineered for dependable high-current switching and isolation in demanding low-voltage power distribution systems.

The E6.2H/MS is a switch-disconnector rather than an automatic circuit breaker fitted with an electronic protection release. Its H-performance construction provides a rated short-time withstand current of 100 kA for 1 s, making it suitable for installations with very high prospective fault currents when coordinated with appropriately rated upstream or downstream protective devices.

This version combines a fixed four-pole configuration with orientable rear horizontal (HR) terminals for integration into high-current switchboards. With a rated operational voltage of up to 690 V AC, the E6.2H/MS 4000 provides robust switching and isolation for industrial plants, transformer distribution, infrastructure, data centres and other critical low-voltage power systems.

High-Current Isolation for Demanding Distribution Systems

The ABB Emax 2 E6.2H/MS is designed for applications requiring dependable high-current switching and circuit isolation without integrated automatic overcurrent protection. Its combination of a 4000 A continuous current rating, operation at up to 690 V AC and 100 kA one-second short-time withstand capability makes it particularly suited to coordinated distribution systems with high prospective fault currents.

The fixed four-pole construction and orientable rear horizontal terminals make the 1SDA073463R1 suitable for integration into substantial low-voltage switchboards and busbar systems. Optional motor operation and voltage-release accessories also allow the switching arrangement to be adapted to applications requiring electrical control, while fault protection can be provided by separately coordinated protective equipment.

Typical Applications

• Main isolation in high-current low-voltage switchboards.
• Four-pole power distribution systems requiring switching and isolation.
• Industrial power distribution installations.
• Transformer secondary distribution systems.
• Bus-section and bus-coupler switching applications.
• Manufacturing plants and heavy process facilities.
• Data centres and critical power infrastructure.
• Large commercial and infrastructure electrical installations.
• Utility and energy distribution systems.
• Switchboards using separately coordinated overcurrent and short-circuit protection.
• High-fault-level installations requiring 100 kA one-second short-time withstand capability.
