Why Choose the ABB E6.2X/MS 5000 4p FHR Switch Disconnector?
The ABB E6.2X/MS 5000 4p FHR, order code 1SDA073466R1, is a high-performance SACE Emax 2 switch disconnector designed for switching and isolation in very high-current low-voltage electrical distribution systems. Built on ABB's E6.2 platform, this fixed four-pole device provides a 5000 A rated uninterrupted current and is engineered for demanding industrial, infrastructure and critical-power switchboards.
The E6.2X/MS configuration is a switch disconnector rather than a protective air circuit breaker equipped with an electronic trip unit. It is designed to make, carry and isolate high-current circuits while overload and short-circuit protection is provided separately within the installation. The X performance level provides an exceptional 120 kA rated short-time withstand current for 1 s, supporting applications with very high prospective fault currents.
The 1SDA073466R1 is supplied in a fixed four-pole configuration with horizontal rear terminals (HR). Rated for operation at up to 690 V AC, with a 1000 V AC insulation voltage and 12 kV impulse withstand voltage, it combines very high current-carrying capacity with robust short-time withstand performance and switchboard integration flexibility.
Key Advantages
- Very high 5000 A rated uninterrupted current for major low-voltage distribution systems.
- Four-pole configuration for switching and isolation in suitable three-phase four-wire networks.
- 120 kA short-time withstand current for 1 s for installations with very high prospective fault currents.
- 100 kA short-time withstand current for 3 s provides strong short-duration fault-current withstand capability.
- Rated for operation at up to 690 V AC.
- Horizontal rear terminals support high-capacity switchboard busbar connections.
- Fixed installation provides a robust solution for permanent high-current switchboard applications.
- Optional motor drive and voltage release support electrically controlled switching arrangements.

Very High-Current Switching and Isolation
Switch disconnectors provide a dependable means of making, carrying and isolating electrical circuits while dedicated protective equipment elsewhere in the installation provides overload and short-circuit protection. In major low-voltage distribution systems, high short-time withstand capability is particularly important where substantial prospective fault currents can occur at main switchboards, transformer secondaries and high-capacity busbar systems.
The ABB E6.2X/MS 5000 combines a 5000 A continuous-current rating with a 120 kA short-time withstand capability for 1 s and 100 kA for 3 s. Its fixed four-pole construction, 50% neutral-pole rating and horizontal rear terminals make it particularly suitable for high-capacity switchboards requiring dependable isolation, very high short-time current withstand performance and efficient rear busbar integration.
Typical Applications
- Main switching and isolation in high-capacity low-voltage switchboards.
- Industrial power distribution systems with high prospective fault currents.
- High-current three-phase four-wire distribution networks.
- Transformer secondary switching and isolation.
- High-current feeder isolation.
- Busbar and bus-section switching applications.
- Large manufacturing and process plant electrical systems.
- Data centres, infrastructure and critical-power distribution systems.
