Why Choose the ABB XT4H-D 250 MCS-UL/CSA 1SDA075624R1 Switch-Disconnector?
The ABB XT4H-D 250 MCS-UL/CSA 1SDA075624R1 is a high-performance 3-pole moulded case switch-disconnector designed for switching, isolation and short-circuit protection in demanding industrial and commercial low-voltage electrical systems. As part of the ABB SACE Tmax XT range, it combines the compact XT4 frame with an MCS magnetic protection function and high interruption capability.
This XT4H-D device has a rated uninterrupted current of 250 A and an instantaneous magnetic trip setting of 3000 A. The MCS configuration provides instantaneous short-circuit protection, making the unit suitable for applications where overload protection is provided separately by coordinated protective equipment.
With a rated operational voltage of 600 V AC, a 3-pole configuration and an H-class interruption rating of 65 kA at 480 V AC, the XT4H-D 250 is suitable for demanding switchboards, machinery and industrial distribution systems. Its fixed construction with front terminals provides straightforward integration into electrical assemblies, while compliance with UL 489 supports applications designed around North American standards.

Reliable Switching and Short-Circuit Protection
Moulded case switch-disconnectors such as the ABB XT4H-D provide switching and isolation together with instantaneous magnetic protection against severe short-circuit currents. The MCS protection function responds rapidly when current reaches the magnetic trip threshold, while appropriately coordinated external protection can be used to provide overload protection where required.
The ABB SACE Tmax XT platform is designed for compact switchboards and industrial electrical systems where dependable switching, high interruption capability and installation flexibility are important. With its 250 A uninterrupted current rating, 3000 A instantaneous magnetic setting and H-class breaking performance, the XT4H-D is well suited to demanding three-phase electrical applications.
Typical Applications
- Industrial low-voltage distribution boards.
- Main and sub-distribution switchboards.
- Three-phase electrical isolation and switching.
- Industrial machinery and production equipment.
- Motor control centres and electrical control panels.
- Commercial and industrial power distribution.
- OEM electrical control and distribution systems.
