1SDA073508R1 ABB E6.2H/MS 4000 3p WMP Switch Disconnector

Why Choose the ABB E6.2H/MS 4000 3p WMP Switch Disconnector?

The ABB E6.2H/MS 4000 3p WMP, order code 1SDA073508R1, is a high-current three-pole withdrawable air switch disconnector from the ABB SACE Emax 2 range. Designed for demanding low-voltage power distribution systems, it provides a substantial 4000 A rated uninterrupted current for major industrial, commercial and infrastructure switchboards.

Built on the E6.2 frame with ABB's H performance level, the E6.2H/MS provides a rated short-time withstand current of 100 kA for 1 s. This high withstand capability makes it suitable for installations with significant prospective fault currents, while appropriately coordinated protective equipment elsewhere in the electrical system provides automatic overload and short-circuit protection.

This model is supplied as a withdrawable moving part (WMP) in a three-pole configuration. With a rated operational voltage of 690 V AC, the 1SDA073508R1 combines high-current switching capability with the maintainability and service flexibility of a withdrawable Emax 2 installation.

Key Advantages

• High-capacity 4000 A rated uninterrupted current for major low-voltage distribution systems.
• 100 kA short-time withstand current for 1 s for demanding high-fault-level installations.

Reliable Withdrawable Isolation for High-Power Distribution

ABB SACE Emax 2 /MS switch disconnectors are engineered for controlled switching and electrical isolation in low-voltage power distribution systems. Unlike an automatic circuit breaker equipped with a protection trip unit, the /MS configuration performs the switching and isolation function while appropriately coordinated protective devices elsewhere in the installation provide the required automatic fault protection.

The withdrawable architecture allows the E6.2H/MS moving portion to be separated from the corresponding fixed switchboard part, supporting inspection, servicing and equipment replacement. Combined with its 4000 A continuous-current capacity and 100 kA 1-second short-time withstand capability, the 1SDA073508R1 is particularly suited to major switchboards where high current capacity, robust fault withstand and serviceable isolation are essential.

Typical Applications

• Main low-voltage distribution switchboards.
• Large industrial power distribution systems.
• High-current incoming and outgoing isolation duties.
• Transformer secondary distribution systems.
• Generator and standby power installations.
• Data centres and critical infrastructure.
• Manufacturing and process plant switchgear.
• Withdrawable high-fault-level distribution assemblies.
