Why Choose the ABB 1SDA100554R1 Tmax XT5S Breaking Part?
The ABB 1SDA100554R1 is a 400 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 a higher interruption capacity than the XT5N range.
Supplied as the breaker body only, the ABB 1SDA100554R1 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 tailored to the application's protection requirements.
Its modular construction provides flexibility for panel builders and electrical engineers, allowing the protection characteristics to be customised while maintaining the proven reliability and compact design of the ABB SACE Tmax XT platform.
Key Advantages
- 400 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 distribution systems.
- Front terminals simplify installation and maintenance.
- Modular design enables customised protection solutions.
Key Features
- ABB SACE Tmax XT5S series.
- 400 A maximum frame rating.
- Three-pole breaking part.
- S-level interruption performance.
- Fixed mounting configuration.
- Front terminal connection.
- Compatible with ABB XT5 trip units.
- Compact modular construction.
Flexible Protection for Custom Circuit Breaker Assemblies
The ABB 1SDA100554R1 provides the switching and fault interruption mechanism required to build a complete XT5S circuit breaker. When combined with a compatible ABB XT5 trip unit, the assembly can be configured to provide thermal-magnetic or advanced electronic protection according to the needs of the installation.
This modular approach enables panel builders to optimise circuit protection, simplify maintenance and standardise components across industrial power distribution systems.
Designed for Higher Fault Levels
The XT5S performance level is intended for installations where greater fault interruption capability is required than the XT5N series. Its robust construction makes it suitable for demanding industrial environments while maintaining the compact dimensions of the XT5 platform.
Typical Applications
- Industrial switchboards.
- Main and sub-main distribution boards.
- Motor control centres.
- OEM electrical equipment.
- Commercial power distribution systems.
- Industrial machinery and process plants.
