1SDA102347R1 ABB XT4X 250 Breaking Part 3-Pole Fixed Front UL/CSA

Why Choose the ABB XT4X 250 Breaking Part 3-Pole UL/CSA?

The ABB XT4X 250 Breaking Part, order code 1SDA102347R1, is a high-performance breaking part for the SACE Tmax XT4 moulded case circuit-breaker platform. Designed for UL/CSA applications, this version features a 250 A frame rating, three-pole construction, fixed installation and front terminals for integration into industrial low-voltage distribution equipment.

As the XT4X high breaking-capacity version, the 1SDA102347R1 provides a rated ultimate short-circuit breaking capacity of 200 kA at 480 V AC. This makes the breaking part particularly suitable for installations where very high prospective fault currents demand a robust interruption capability.

The unit is designed for use as the breaking element of a correctly configured Tmax XT4 protection assembly and can be combined with compatible ABB trip units and accessories. Its UL 489 and CSA C22.2 platform is intended for North American and other installations requiring UL/CSA-approved low-voltage circuit-breaker configurations.

High Breaking Capacity for Demanding Power Systems

The breaking part is the power-interruption element within a configured moulded case circuit breaker. When combined with the appropriate ABB protection and operating components, it provides the mechanism required to interrupt the main circuit under fault conditions and isolate downstream equipment from damaging short-circuit currents.

With an XT4X breaking capacity of 200 kA at 480 V AC, the 1SDA102347R1 is designed for demanding installations with high prospective fault levels. Its compact XT4 format, fixed construction and front connections make it suitable for integration into industrial switchboards, distribution panels and machinery power systems.

Typical Applications

• Industrial low-voltage power-distribution systems.
• Switchboards with high prospective short-circuit currents.
• Three-phase electrical distribution panels.
• Industrial machinery and automation power systems.
• Manufacturing and process-industry installations.
• Commercial and infrastructure distribution equipment.
• UL/CSA-compliant circuit-breaker assemblies.
