The ABB 1SDA105128R1, designated SUPP.INTERL. B-D XT7-XT7M F, is a mechanical interlock support designed for ABB SACE Tmax XT7 and XT7M circuit breakers. It forms part of a cable-operated mechanical interlocking system between two circuit breakers, helping prevent operating combinations that are not permitted by the selected interlock scheme.
This version is specifically designed for Type B and Type D mechanical interlock configurations and is intended for the fixed part of an XT7 or XT7M installation. Used with the appropriate ABB mechanical interlock components, it provides the mounting and operating interface required to implement a coordinated interlock between two compatible circuit breakers.
The 1SDA105128R1 measures approximately 50 mm × 270 mm × 400 mm and has a product weight of approximately 0.9 kg. Its genuine ABB construction makes it suitable for engineered switchboard applications where dependable mechanical interlocking is required between SACE Tmax XT7 or XT7M circuit breakers.
Mechanical interlocking is used where the operating states of two circuit breakers must be physically coordinated. A cable-operated interlock transfers the mechanical state between the breakers, helping prevent prohibited combinations without relying solely on electrical control logic.
The ABB 1SDA105128R1 provides the support required for Type B or Type D interlocking on compatible XT7 and XT7M fixed-part arrangements. A complete two-breaker interlocking system requires the appropriate ABB cable and corresponding interlock supports selected for the required circuit-breaker configuration.
