1SDA073472R1 ABB E6.2X/f/MS 5000 4p F HR Switch Disconnector

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

The ABB E6.2X/f/MS 5000 4p F HR, order code 1SDA073472R1, 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 and X performance level, it provides exceptional current-carrying and short-time withstand capability for major industrial, commercial and infrastructure switchboards.

The E6.2X/f/MS is a switch-disconnector configuration designed to satisfy the isolation requirements associated with IEC 60947-3. The /f configuration provides a fully rated fourth pole / full-size neutral, while its fixed construction and orientable rear horizontal terminals support integration into high-current switchboards and busbar systems.

With a rated uninterrupted current of 5000 A, a four-pole configuration and a rated short-time withstand current of 120 kA for 1 s, the E6.2X/f/MS is designed for extremely demanding low-voltage distribution applications. Its combination of high continuous-current capacity and exceptional withstand performance makes it particularly suitable for critical high-power installations.

Key Advantages

• High-capacity 5000 A air switch disconnector for major low-voltage distribution systems.

Reliable High-Current Switching and Isolation

ABB Emax 2 /MS switch disconnectors 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 primarily intended to establish, interrupt and isolate the electrical path as part of a coordinated power distribution system.

The E6.2X/f/MS platform combines a substantial 5000 A continuous-current rating with an exceptional 120 kA short-time withstand capability. This makes the 1SDA073472R1 particularly suitable for high-capacity main distribution boards, industrial switchgear and critical infrastructure where robust high-current isolation and strong fault-withstand performance are 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.
