The ABB 1SDA066639R1 is a MIR-P mounting plate for mechanical interlocking, specifically designed for ABB Tmax XT1 fixed moulded-case circuit breakers. As part of the ABB Tmax XT mechanical accessory range, it provides the breaker-specific mounting interface required when incorporating a fixed XT1 circuit breaker into a compatible rear mechanical interlocking system.
Mechanical interlocking is used where the operating states of two circuit breakers must be mechanically coordinated. The 1SDA066639R1 is the XT1 fixed-breaker plate used with ABB's compatible MIR-HR horizontal or MIR-VR vertical interlock frame assemblies, helping create an interlocking arrangement that prevents prohibited simultaneous breaker states.
Designed specifically for the ABB Tmax XT1 fixed (F) configuration, the MIR-P plate provides purpose-designed compatibility with the breaker and ABB interlocking hardware. For a two-breaker mechanical interlock, the appropriate interlock frame and a suitable MIR-P plate for each circuit breaker are required.
Mechanical interlocking provides a physical method of coordinating the operating states of circuit breakers without relying solely on electrical control logic. In a compatible ABB Tmax XT arrangement, the interlock mechanism mechanically restricts breaker operation according to the configured switching sequence, making it useful in applications where two power sources or circuits must not be connected simultaneously.
The ABB 1SDA066639R1 provides the dedicated mounting plate required for a fixed XT1 circuit breaker within the compatible rear interlock system. A complete two-breaker installation requires an appropriate MIR-HR or MIR-VR frame assembly together with the correct MIR-P plate for each circuit breaker being interlocked.

The ABB 1SDA066639R1 is a MIR-P mounting plate for mechanical interlocking of an ABB Tmax XT1 fixed moulded-case circuit breaker.
The 1SDA066639R1 is specifically designed for the ABB Tmax XT1 fixed circuit-breaker configuration.
No. The 1SDA066639R1 is the breaker-specific MIR-P mounting plate. A complete two-breaker interlock requires the appropriate ABB MIR-HR horizontal or MIR-VR vertical frame assembly and a suitable MIR-P plate for each circuit breaker.
Yes. The XT1 fixed MIR-P plate can form part of compatible ABB horizontal or vertical rear mechanical interlocking arrangements when combined with the appropriate interlock frame.
A mechanical interlock physically coordinates circuit-breaker operation and can prevent prohibited simultaneous breaker states, making it particularly useful in changeover, source-selection and controlled power distribution systems.
ABB Tmax XT mechanical interlocking accessories provide purpose-designed coordination between compatible moulded-case circuit breakers, supporting dependable source changeover and controlled switching in low-voltage power distribution systems.
