1SDA068292R1 ABB XT4L 160 3-Pole Fixed Breaking Part with Front Terminals

Why Choose the ABB XT4L 160 Breaking Part 3p F F?

The ABB 1SDA068292R1 XT4L 160 BREAKING PART 3p F F is a three-pole breaking part for the ABB SACE Tmax XT4 moulded case circuit breaker system. Designed as the switching and fault-interruption section of a modular XT4 assembly, it provides the breaker mechanism and L-level short-circuit performance while allowing a compatible ABB XT4 trip unit to be selected separately to suit the protection requirements of the installation.

The XT4L 160 breaking part has a rated uninterrupted current of 160 A and delivers an ultimate short-circuit breaking capacity of 120 kA at 415 V AC. Its high L performance level makes it particularly suitable for industrial and commercial distribution systems where high prospective fault currents demand substantial interruption capability.

Configured with three poles, fixed mounting and front terminals, the 1SDA068292R1 is designed for straightforward integration into low-voltage switchboards and distribution panels. It supports rated operational voltages up to 690 V AC and must be combined with a compatible ABB XT4 trip unit to create a complete protected moulded case circuit breaker assembly.

High-Performance Modular Breaking Part for Tmax XT4

The ABB XT4L breaking part provides the switching mechanism and high-capacity fault-current interruption section of a modular Tmax XT4 circuit breaker. Its 120 kA Icu and Ics at 415 V AC make it particularly well suited to installations where substantial short-circuit levels must be accommodated, while its modular design allows the protection release to be chosen according to the specific requirements of the circuit.

The 1SDA068292R1 is not a complete protected circuit breaker when supplied as the breaking part alone. A compatible ABB SACE Tmax XT4 trip unit must be installed to provide the required overload and/or short-circuit protection functions. This modular approach allows the breaking part and protection release to be configured for the application while retaining the compact XT4 platform.

Typical Applications

• Industrial low-voltage switchboards.
• Main and sub-distribution panels.
• Three-phase electrical distribution systems.
• Manufacturing and production facilities.
• Commercial electrical distribution systems.
• Machinery and automation power distribution.
• Infrastructure and building electrical systems.
• Installations with high prospective short-circuit currents.
• Custom ABB SACE Tmax XT4 circuit breaker assemblies.
