1SDA100547R1 ABB XT5D 630 630 A 3-Pole Switch-Disconnector

Why Choose the ABB XT5D 630 1SDA100547R1 Switch-Disconnector?

The ABB XT5D 630 1SDA100547R1 is a 630 A three-pole switch-disconnector designed for reliable switching and isolation in low-voltage electrical distribution systems. Part of the ABB SACE Tmax XT series, it uses the XT5 moulded-case platform and is supplied in a fixed configuration with front terminals for straightforward integration into industrial and commercial switchboards.

Unlike a protective MCCB fitted with an overcurrent trip unit, the XT5D is a moulded-case switch / switch-disconnector whose principal functions are load switching and circuit isolation. This makes it suitable for installations where dependable disconnection is required while overload and short-circuit protection are provided by appropriately coordinated protective devices elsewhere in the system.

The 1SDA100547R1 is rated at 630 A and supports both AC-22A and AC-23A operation at 415/440 V AC and 690 V AC. Its three-pole fixed construction with front terminals, combined with a rated short-time withstand current of 7.6 kA for 1 second, provides a robust isolation solution for high-current low-voltage distribution applications.

Key Advantages

• 630 A switch-disconnector for dependable high-current switching and isolation.
• ABB SACE Tmax XT5 platform provides compact integration with compatible switchboard systems and accessories.
• Rated for 630 A AC-22A operation at both 415/440 V AC and 690 V AC.

Reliable High-Current Switching and Isolation

A switch-disconnector provides controlled load switching together with an isolation function, allowing sections of an electrical installation to be disconnected for operation, servicing or maintenance. The ABB XT5D is derived from the Tmax XT moulded-case platform, retaining a compact form factor and compatibility with the wider system architecture while providing dedicated switching and disconnection functionality.

The XT5D 630 is specifically a switch-disconnector rather than an overcurrent-protective circuit breaker. Applications requiring automatic overload or short-circuit protection therefore need appropriately coordinated protective devices within the installation. With its 630 A current rating, AC and DC utilisation ratings and 7.6 kA 1-second withstand capability, the 1SDA100547R1 is particularly suited to main isolation and high-current feeder switching duties.

Typical Applications

• Main switch and isolation duties in low-voltage switchboards.
• Industrial electrical distribution systems.
• High-current feeder and distribution-circuit isolation.
• Machinery and process-system isolation.
• Commercial and infrastructure distribution panels.
• AC and compatible DC switching applications requiring a 630 A switch-disconnector.
