Why Choose the ABB 1SDA066646R1 MIR-P x XT4 P/W Mechanical Interlock Plate?

The ABB 1SDA066646R1 is a MIR-P mechanical interlock plate designed specifically for ABB SACE Tmax XT4 moulded-case circuit breakers. It is intended for plug-in and withdrawable (P/W) XT4 configurations and provides the breaker-specific interface required within an ABB rear mechanical interlocking arrangement.

Mechanical interlocking is used to coordinate the operating states of compatible circuit breakers, helping prevent operating combinations that should not occur simultaneously. The MIR-P plate connects the applicable XT4 breaker configuration to the corresponding ABB mechanical interlock frame, making it an essential component when assembling the complete interlocking system.

As part of the ABB T-Max XT 250 Range, the 1SDA066646R1 is purpose-designed for Tmax XT4 plug-in or withdrawable circuit breakers. It is suitable for switchboards, transfer arrangements and industrial distribution systems where dependable mechanical coordination between circuit breakers is required.

Reliable Mechanical Circuit-Breaker Interlocking

The ABB MIR-P system provides breaker-specific mounting plates for mechanical interlocking arrangements within the Tmax XT family. For the 1SDA066646R1, the plate is configured specifically for an XT4 circuit breaker in a plug-in or withdrawable installation, ensuring compatibility with the intended mechanical interlock assembly.

When used with the appropriate ABB interlock frame and corresponding plate for the other circuit breaker, the MIR-P plate enables a mechanically coordinated interlocking arrangement. This makes it suitable for transfer, source-selection and other switchgear applications where physical interlocking between circuit breakers is required.

Typical Applications

  • ABB SACE Tmax XT4 plug-in circuit breakers.
  • ABB SACE Tmax XT4 withdrawable circuit breakers.
  • Rear mechanical circuit-breaker interlocking systems.
  • Source transfer and changeover arrangements.
  • Industrial electrical distribution boards.
  • Switchboards with mechanically interlocked breakers.
  • Commercial and industrial low-voltage switchgear.
