1SDA073552R1 ABB E6.2X/MS 6300 4p WMP Switch Disconnector

Why Choose the ABB E6.2X/MS 6300 4p WMP Switch Disconnector?

The ABB E6.2X/MS 6300 4p WMP, order code 1SDA073552R1, is a high-performance four-pole withdrawable air switch disconnector from the ABB SACE Emax 2 family, engineered for high-current switching and electrical isolation in demanding low-voltage power distribution systems. Built on the Emax 2 E6.2 platform, it provides a substantial 6300 A rated uninterrupted current together with the exceptional short-time withstand capability of the X performance level.

The E6.2X/MS is a switch-disconnector configuration designed to meet the isolation requirements of IEC 60947-3 rather than provide automatic overcurrent protection. The 1SDA073552R1 is the withdrawable moving part for use with the appropriate Emax 2 fixed part, enabling convenient disconnection for inspection, servicing and maintenance in high-capacity switchboards.

With a rated operational voltage of 690 V AC, rated insulation voltage of 1000 V AC and rated short-time withstand current of 120 kA for 1 s, the E6.2X/MS is designed for installations with exceptionally demanding prospective fault levels. Its four-pole configuration and X performance level make it a powerful switching and isolation solution for major low-voltage distribution systems.

Key Advantages

• High-capacity 6300 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 Emax 2 air circuit breaker equipped with a protection trip unit, the /MS configuration omits the protection release and is designed to establish, carry, interrupt and isolate the electrical path in accordance with switch-disconnector requirements.

The withdrawable E6.2X/MS architecture allows the moving part to be separated from its compatible fixed part, supporting efficient inspection, servicing and equipment replacement. Combined with its 6300 A current rating, 120 kA one-second withstand capability and X performance level, the 1SDA073552R1 provides a powerful solution for high-fault-level low-voltage distribution assemblies.

Typical Applications

• High-capacity main low-voltage distribution switchboards.
• Heavy industrial power distribution systems.
• Data centres and mission-critical infrastructure.
• Large commercial and infrastructure installations.
• High-current four-pole circuit isolation and sectionalising.
• OEM withdrawable switchgear and power distribution assemblies.
