1SDA118425R1 ABB XT4 Extra Code for ML Version

Why Choose the ABB 1SDA118425R1 XT4 ML Version Extra Code?

The ABB 1SDA118425R1 is the dedicated extra ordering code for the ML version of ABB SACE Tmax XT4 moulded-case circuit breakers. It is used when specifying an XT4 breaker with the ML certification and marking required for specialised naval and marine electrical applications.

The ML range is based on the established ABB SACE Tmax XT platform and is developed for demanding naval electrical distribution environments where dependable protection, continuity of service and robust equipment are important. ABB specifies the same accessory range, configuration rules and ordering codes as the standard SACE Tmax XT family, with the appropriate ML extra code added to the breaker order.

The 1SDA118425R1 is therefore a configuration and ordering code rather than a standalone circuit breaker or physical accessory. It is specifically associated with compatible three-pole XT4 breakers requiring the ML version designation.

Key Advantages

• Official ABB SACE Tmax XT4 ML extra ordering code.

ML Configuration for ABB SACE Tmax XT4

ABB SACE Tmax XT ML circuit breakers are intended for electrical distribution aboard naval vessels and other demanding marine environments. The ML family combines the established protection technology of the Tmax XT platform with certification and marking appropriate to these specialised applications.

The ABB 1SDA118425R1 identifies the XT4 ML version within the ordering configuration. The electrical ratings, trip unit, breaking capacity and other breaker characteristics are determined by the associated XT4 circuit breaker selected alongside this extra code.

Typical Applications

• ABB SACE Tmax XT4 ML circuit breaker configurations.
• Naval vessel electrical distribution systems.
• Marine low-voltage switchboards.
• Mission-critical onboard electrical infrastructure.
• Shipboard machinery and auxiliary power systems.
• Panel building requiring an ML-certified XT4 configuration.
