1SDA058910R1 ABB E6H/f/MS 4000 4000A 4-Pole Withdrawable Switch-Disconnector Moving Part

Why Choose the ABB E6H/f/MS 4000 4-Pole Withdrawable Switch-Disconnector?

The ABB E6H/f/MS 4000 is a heavy-duty 4000 A four-pole switch-disconnector moving part designed for high-current switching and isolation in demanding low-voltage power-distribution systems. Part of the ABB SACE Emax E6 series, this H-performance full-size-neutral configuration combines substantial current-carrying capability with a withdrawable construction for integration into critical industrial, commercial and infrastructure switchgear.

Unlike an Emax automatic circuit breaker fitted with an electronic overcurrent release, the E6H/f/MS is a switch-disconnector intended for switching and isolation. ABB Emax /MS devices are derived from the corresponding air circuit breakers, retaining their mechanical platform and accessory compatibility while omitting the overcurrent trip unit, and are designed for switch-disconnector duties in accordance with IEC 60947-3.

The 1SDA058910R1 configuration is rated at 4000 A and features a four-pole withdrawable moving part with a full-size neutral pole. With a rated operational voltage of 690 V AC, a 100 kA one-second short-time withstand current and a 220 kA peak short-circuit making capacity, it is engineered for high-power distribution systems with demanding prospective fault levels.

High-Current Switching and Isolation with Full-Size Neutral

ABB SACE Emax /MS switch-disconnectors are based on the corresponding Emax air circuit-breaker platform but operate without an integrated overcurrent trip unit. This construction provides high-current switching and isolation while allowing the device to use the established Emax mechanical architecture and compatible accessories. The E6H/f/MS performance level is particularly suited to installations with substantial prospective short-circuit currents.

The E6H/f/MS 4000 combines its 4000 A current rating with a full-size fourth pole, 100 kA one-second withstand capability and 220 kA peak making capacity. Its withdrawable construction allows the moving part to be separated from the corresponding fixed part for maintenance or replacement, making it well suited to critical switchboards where high electrical performance and serviceability are required.

Typical Applications

• Main low-voltage distribution switchboards.
• High-current industrial power distribution systems.
• Main incomer and bus-coupler switching.
• Four-pole circuits requiring a full-size neutral pole.
• Manufacturing and heavy process plants.
• Commercial and infrastructure power systems.
• Withdrawable switchgear and power distribution centres.
• High-fault-level installations requiring strong short-time withstand performance.
