1SDA073471R1 ABB E6.2H/f/MS 5000 4p F HR Switch Disconnector

Why Choose the ABB E6.2H/f/MS 5000 4p F HR Switch Disconnector?

The ABB E6.2H/f/MS 5000 4p F HR, order code 1SDA073471R1, is a high-capacity four-pole air switch disconnector from the ABB SACE Emax 2 family, engineered for dependable switching and isolation in demanding low-voltage power distribution systems. Based on the large E6.2 frame, it provides the current-carrying capacity and short-time withstand performance required for major industrial, commercial and infrastructure switchboards.

This E6.2H/f/MS model is a fixed switch-disconnector configuration designed for controlled switching and electrical isolation rather than automatic overcurrent protection. The four-pole arrangement incorporates a full-size neutral, while the rear horizontal terminals provide a practical high-current connection arrangement for integration into compatible switchgear and busbar systems.

With a rated uninterrupted current of 5000 A, a rated operational voltage of 690 V AC and a rated short-time withstand current of 100 kA, the E6.2H/f/MS is designed for exceptionally demanding distribution applications. Its combination of high continuous-current capability, robust fixed construction and Emax 2 architecture makes it suitable for critical high-power installations.

Reliable High-Current Switching and Isolation

ABB Emax 2 /MS switch disconnectors are designed to provide dependable switching and electrical isolation of low-voltage power circuits. Unlike an automatic air circuit breaker equipped with a protection trip unit, the /MS configuration is intended primarily to establish, interrupt and isolate the electrical path as part of a coordinated power distribution system.

The E6.2H/f/MS platform combines a substantial 5000 A continuous-current rating with 100 kA short-time withstand capability. This makes the 1SDA073471R1 particularly suitable for high-capacity main distribution boards, industrial switchgear and critical infrastructure where robust high-current isolation is required.

Typical Applications

• High-capacity main low-voltage distribution switchboards.
• Industrial power distribution systems.
• Data centres and critical infrastructure.
• Commercial and utility electrical installations.
• High-current circuit isolation and sectionalising.
• OEM switchgear and power distribution assemblies.
