Why Choose the ABB XT5 Extra Code for ML Version?
The ABB 1SDA118426R1 is the dedicated XT5 extra ordering code for the SACE Tmax XT ML version. It is used when specifying an eligible three-pole ABB SACE Tmax XT5 circuit breaker with the ML certification and marking required for naval and demanding marine electrical applications.
ABB's SACE Tmax XT ML range is developed for electrical distribution aboard naval vessels and other critical marine environments where continuity of service, compact dimensions and dependable protection are important. The 1SDA118426R1 extra code identifies the XT5 ML requirement alongside the normal ordering codes for the circuit breaker, trip unit, execution and accessories.
The ML extra code does not replace the underlying XT5 circuit-breaker order codes and is not a standalone circuit breaker or physical accessory. ABB specifies that accessories, configuration rules and ordering codes remain the same as for the standard SACE Tmax XT family, with 1SDA118426R1 added to the order to define the applicable XT5 ML version.
Key Advantages
- Official ABB extra ordering code for the SACE Tmax XT5 ML version.
- Used to specify eligible XT5 circuit breakers with ML certification and marking.

- Provides a clear ordering reference for distinguishing an eligible XT5 ML configuration from the standard version.
Key Features
- ABB SACE Tmax XT ML range.
- Dedicated to the XT5 frame size.
- Extra ordering code rather than a standalone circuit breaker.
- Applicable to eligible three-pole XT5 circuit breakers.
- Used for ML certification and marking.
- Designed for naval and demanding marine power distribution applications.
- Standard Tmax XT accessories and configuration rules remain applicable.
- XT5 ML circuit breakers are available in fixed, plug-in and withdrawable executions.
- Supports compatible XT5 ML configurations with rated uninterrupted currents of 400 A and 630 A.
SACE Tmax XT5 ML for Naval Electrical Distribution
The SACE Tmax XT ML family is ABB's low-voltage circuit-breaker range developed for naval applications and critical marine environments. ABB specifies ML certification and marking for eligible three-pole circuit breakers across the Tmax XT range, while retaining the familiar configuration rules and accessory ecosystem of the standard Tmax XT family.
For an XT5 ML configuration, 1SDA118426R1 is added as an extra ordering code alongside the required breaker components. For example, an XT5 ML assembly may include the XT5 breaking part, an appropriate trip unit, conversion or moving-part components where required, the 1SDA118426R1 ML extra code and the relevant fixed part, depending on the selected circuit-breaker execution.
Typical Applications
- ABB SACE Tmax XT5 ML circuit-breaker configurations.
- Naval vessel low-voltage electrical distribution systems.
- Marine switchboards and distribution assemblies.
- Mission-critical onboard electrical infrastructure.
- Marine power systems requiring eligible ML-certified and marked circuit breakers.
- Fixed, plug-in or withdrawable three-pole XT5 ML installations.
