Why Choose the ABB 1SDA100555R1 Tmax XT5S Breaking Part?
The ABB 1SDA100555R1 is a 630 A frame-size breaking part for ABB SACE Tmax XT5 moulded case circuit breaker assemblies. Part of the ABB Tmax XT5S range, this fixed three-pole breaking part is designed for industrial and commercial low-voltage power distribution systems requiring enhanced short-circuit interruption performance.
Supplied as the breaker body only, the ABB 1SDA100555R1 does not include a protection trip unit. A compatible ABB XT5 electronic or thermal-magnetic trip unit must be selected separately to create a complete moulded case circuit breaker configured to suit the application's protection requirements.
Its modular construction enables panel builders and electrical engineers to tailor circuit protection while benefiting from the compact dimensions, dependable operation and proven performance of the ABB SACE Tmax XT platform.
Key Advantages
- 630 A frame-size breaking part for ABB XT5 circuit breaker assemblies.
- Higher XT5S interruption-performance level for demanding installations.
- Compatible with ABB XT5 electronic and thermal-magnetic trip units.
- Three-pole fixed configuration for industrial power distribution.
- Front terminals simplify cable and busbar connections.
- Modular design supports customised protection solutions.

Flexible Protection for Custom Circuit Breaker Assemblies
The ABB 1SDA100555R1 provides the switching and interruption mechanism required to build a complete XT5S circuit breaker. When paired with a compatible ABB XT5 trip unit, the assembly can be configured with thermal-magnetic or advanced electronic protection to match the application's operating requirements.
This modular approach enables panel builders to standardise components while configuring protection characteristics for individual installations, simplifying both maintenance and future upgrades.
The XT5S performance level is intended for electrical systems where greater short-circuit interruption capability is required than the XT5N range. Its robust construction makes it well suited to demanding industrial and commercial installations while maintaining the compact footprint of the XT5 platform.
Typical Applications
- Industrial switchboards.
- Main and sub-main distribution boards.
- Motor control centres.
- Commercial power distribution systems.
- OEM electrical equipment.
- Manufacturing and process plants.
