1SDA100548R1 ABB XT5D 400 4p F F Switch-Disconnector

Why Choose the ABB XT5D 400 4p F F Switch-Disconnector?

The ABB XT5D 400 4p F F, order code 1SDA100548R1, is a robust four-pole switch-disconnector from the ABB SACE Tmax XT family. Built on the XT5 platform, it is designed for reliable switching and isolation of low-voltage electrical circuits in industrial and commercial power distribution systems.

With a rated uninterrupted current of 400 A, the XT5D provides dependable load switching and circuit isolation without an integrated overcurrent protection trip unit. This makes it suitable for installations where circuit protection is provided separately and a dedicated switching and isolation device is required.

The XT5D 400 is supplied in a fixed four-pole configuration with front terminals. It supports a rated operational voltage of up to 690 V AC and has a rated short-time withstand current of 5 kA, providing a robust solution for switchboards and electrical distribution assemblies.

Reliable Switching and Isolation for Low-Voltage Systems

Switch-disconnectors such as the ABB XT5D provide a means of switching electrical loads and positively isolating circuits for maintenance, servicing and system control. Unlike a protective circuit breaker, the XT5D is intended primarily for switching and isolation, with overcurrent and short-circuit protection provided by suitable upstream or associated protective devices.

The SACE Tmax XT5 platform is designed for integration into modern switchboards and power distribution assemblies. Its fixed mounting arrangement, four-pole construction and front terminals support practical panel installation while providing reliable isolation of electrical circuits in demanding industrial and commercial environments.

Typical Applications

• Industrial low-voltage switchboards.
• Commercial power distribution panels.
• Main and sub-distribution isolation.
• Machine and production-line electrical systems.
• Electrical control panels and distribution assemblies.
• Four-pole AC distribution circuits.
• Systems requiring dedicated load switching and circuit isolation.
