1SDA105122R1 ABB MIR-P XT5 F Mechanical Interlock Plate

Why Choose the ABB 1SDA105122R1 MIR-P XT5 Mechanical Interlock Plate?

The ABB 1SDA105122R1, designated MIR-P x XT5 F, is a mounting plate for the mechanical interlock system of ABB SACE Tmax XT5 fixed circuit breakers. Designed specifically for the XT5 platform, it forms part of ABB's rear mechanical interlocking solution for applications where the operation of interconnected circuit breakers must be mechanically coordinated.

Mechanical interlocking is commonly used in power distribution and changeover arrangements to prevent incompatible circuit breaker operating states. The MIR-P plate provides the dedicated interface required on a fixed-version XT5 circuit breaker when it is incorporated into a compatible ABB mechanical interlock system.

As a genuine ABB SACE Tmax XT mechanical accessory, the 1SDA105122R1 is engineered for precise integration with the XT5 frame. The plate measures 200 × 10 × 250 mm (W × H × D), has a net weight of approximately 0.57 kg and is designed for circuit breaker installations conforming to IEC 60947-2 requirements.

Reliable Mechanical Interlocking for Power Distribution

Mechanical interlocking provides a physical means of coordinating the operation of circuit breakers, helping prevent operating combinations that are not permitted by the electrical system design. This is particularly valuable in switchboards incorporating alternative supplies, changeover arrangements and other applications where two circuit breakers must operate according to a defined interlocking sequence.

The ABB 1SDA105122R1 provides the dedicated MIR-P mounting plate for a fixed XT5 circuit breaker. When combined with the appropriate ABB mechanical interlock components, it enables the XT5 to form part of a robust rear mechanical interlocking arrangement for professional low-voltage distribution systems.

Typical Applications

• ABB SACE Tmax XT5 fixed circuit breaker installations.
• Rear mechanical interlocking systems.
• Electrical source changeover arrangements.
• Industrial low-voltage switchboards.
• Power distribution and protection panels.
• Installations requiring mechanically coordinated circuit breaker operation.
