Why Choose the ABB 1SDA100268R1 XT4X 250 Breaking Part?
The ABB 1SDA100268R1 is a SACE Tmax XT4X 250 breaking part designed as the switching and fault-interruption section of a modular XT4 moulded-case circuit breaker assembly. It is supplied in a fixed, four-pole configuration with front terminals and is intended for combination with compatible ABB XT4 protection and trip-unit solutions.
As part of the ABB SACE Tmax XT series, the XT4X combines compact construction with exceptionally high short-circuit interruption performance. The X performance level provides an ultimate short-circuit breaking capacity of 200 kA at 415 V AC, making this breaking part particularly suitable for demanding low-voltage distribution systems with very high prospective fault currents.
The 1SDA100268R1 is the 250 A, 4-pole version of the XT4X breaking part. Its fixed execution and front main-circuit connections support conventional switchboard integration, while its modular architecture allows the breaking part to be combined with a compatible XT4 trip unit selected according to the protection requirements of the complete circuit-breaker assembly.

Ultra-High Breaking Performance for Modular XT4 Protection
Unlike a complete circuit breaker supplied with a specified Ekip or thermal-magnetic trip unit, the ABB 1SDA100268R1 is identified as an XT4X breaking part. It provides the principal switching and fault-interruption section of the circuit breaker and can be combined with compatible ABB XT4 protection components selected to suit the protection requirements of the installation.
The XT4X performance level is designed for installations where exceptionally high prospective short-circuit currents demand maximum interruption capability from the XT4 platform. With 200 kA Icu at 415 V AC, a 250 A frame size, four-pole construction, fixed mounting and front terminals, the 1SDA100268R1 provides a robust foundation for high-performance ABB Tmax XT4 circuit-breaker assemblies.
Typical Applications
- High-fault-level low-voltage distribution switchboards.
- Industrial main and sub-distribution assemblies.
- Commercial and infrastructure power distribution.
- Manufacturing and process-industry switchgear.
- Transformer-fed distribution systems.
- Four-pole switching and isolation applications.
- Custom ABB SACE Tmax XT4 circuit-breaker configurations.
- Systems requiring exceptionally high short-circuit interruption capability.
