1SDA118428R1 ABB XT7 Extra Code for ML Version

Why Choose the ABB XT7 Extra Code for ML Version?

The ABB 1SDA118428R1, designated XT7 Extra Code for ML Version, is an ordering extra code used to specify an ABB SACE Tmax XT7 circuit breaker in the ML version. It forms part of ABB’s SACE Tmax XT ML offering, developed for low-voltage electrical distribution in naval and marine applications where dedicated certification and marking are required.

The extra code is added to the ordering configuration of a compatible XT7 circuit breaker rather than functioning as a standalone electrical accessory. ABB specifies that ML certification and marking are available for three-pole SACE Tmax XT circuit breakers, with accessories, configuration rules and ordering codes remaining consistent with the wider SACE Tmax XT family.

Using the 1SDA118428R1 extra code identifies the associated XT7 configuration as an ML version. The SACE Tmax XT ML range is designed for demanding naval electrical installations and provides the protection, availability and continuity-of-service capabilities of the Tmax XT platform while supporting the certification requirements applicable to ML configurations.

ML Configuration for Naval Electrical Distribution

ABB’s SACE Tmax XT ML range is designed for low-voltage electrical distribution in naval applications, where high availability and continuity of service are important. The ML offering uses the established Tmax XT circuit breaker platform while providing the certification and marking required for the dedicated ML configuration.

The 1SDA118428R1 is specifically the extra ordering code for the XT7 ML version. It is used alongside the appropriate XT7 circuit breaker ordering configuration to identify the required ML-certified version and does not replace the ordering code for the circuit breaker itself.

Typical Applications

• Naval low-voltage electrical distribution systems.
• Marine switchboards using ABB SACE Tmax XT7 circuit breakers.
• Shipboard power distribution installations.
• Electrical systems requiring an ABB XT7 ML configuration.
• Naval switchgear assemblies requiring dedicated certification and marking.
• Three-pole XT7 circuit breaker configurations specified for ML applications.
