Why Choose the ABB 1SDA100553R1 Tmax XT5N Breaking Part?
The ABB 1SDA100553R1 is a 630 A frame-size breaking part for ABB SACE Tmax XT5 moulded case circuit breaker assemblies. Designed as part of the ABB Tmax XT5N range, it features a fixed four-pole configuration with front terminals for integration into industrial and commercial low-voltage power distribution systems.
Unlike a complete moulded case circuit breaker, the ABB 1SDA100553R1 is supplied as the breaker body or breaking part and does not include a protection trip unit. A compatible ABB XT5 trip unit must be selected separately according to the required rated current, protection functions and system-coordination requirements.
The four-pole construction allows all three phase conductors and the neutral conductor to be switched together. With its XT5N interruption-performance level, robust operating mechanism and compact format, this breaking part provides a flexible foundation for building a customised circuit protection solution.
Key Advantages
- 630 A frame-size breaking part for ABB Tmax XT5 assemblies.

- Four-pole configuration for simultaneous switching of phases and neutral.
- Fixed mounting arrangement for dependable switchboard installation.
- Front terminals simplify cable and busbar connections.
- Modular design enables tailored protection solutions.
Key Features
- ABB SACE Tmax XT5N series.
- 630 A maximum frame rating.
- Four-pole breaking part.
- Normal (N) interruption-performance level.
- Fixed installation configuration.
- Front terminal arrangement.
- Compatible with ABB XT5 protection trip units.
- Designed for modular MCCB assembly.
A Flexible Foundation for Circuit Protection
The ABB 1SDA100553R1 provides the switching and interruption mechanism for a customised XT5 circuit breaker assembly. By selecting a compatible ABB XT5 trip unit separately, engineers can configure the protection characteristics to suit the installation's electrical requirements.
This modular approach allows overload, short-circuit and advanced electronic protection functions to be selected according to the application while simplifying maintenance and future upgrades.
Designed for Three-Phase Distribution Systems
Its four-pole design enables simultaneous switching of all three phase conductors together with the neutral conductor, making it suitable for three-phase, four-wire power distribution systems where neutral isolation is specified.
The fixed construction and front terminal arrangement provide straightforward integration into industrial switchboards, commercial distribution panels and OEM equipment.
Typical Applications
- Industrial switchboards.
- Main and sub-main distribution boards.
- Commercial electrical installations.
- Motor control centres.
- OEM machinery.
- Low-voltage power distribution systems.
