Why Choose the ABB 1SDA066645R1 MIR-P Mechanical Interlock Plate?

The ABB 1SDA066645R1 is a MIR-P mechanical interlock plate designed specifically for ABB SACE Tmax XT4 moulded-case circuit breakers. Intended for a fixed (F) XT4 circuit breaker, the plate forms part of ABB's rear mechanical interlocking system for applications where the operating states of two circuit breakers need to be mechanically coordinated.

As part of the ABB T-Max XT 250 Range, the MIR-P plate provides the breaker-specific interface required when assembling a compatible mechanical interlock system. ABB specifies a suitable MIR-HR horizontal or MIR-VR vertical interlock frame together with an appropriate MIR-P plate for each circuit breaker being interlocked.

The 1SDA066645R1 is purpose-designed for the ABB Tmax XT4 fixed configuration, providing the correct mechanical interface between the breaker and the interlocking assembly. It is suitable for switchboards, transfer arrangements and distribution systems where mechanical interlocking helps prevent incompatible circuit-breaker operating states.

Key Advantages

  • Genuine ABB MIR-P mechanical interlock plate for SACE Tmax XT.
  • Designed specifically for the XT4 circuit-breaker frame.
  • Compatible with fixed (F) XT4 circuit breakers.
  • Provides the breaker-specific plate required for ABB rear mechanical interlocking.
  • Supports mechanically coordinated operation between compatible circuit breakers.
  • Purpose-engineered for integration with the ABB Tmax XT mechanical interlock system.

Key Features

  • ABB SACE Tmax XT mechanical accessory.
  • MIR-P mechanical interlock plate.
  • Compatible with Tmax XT4.
  • Designed for fixed circuit-breaker installation.
  • Used as part of a rear mechanical interlock arrangement.
  • One appropriate MIR-P plate is required for each breaker in the interlock arrangement.
  • Compatible with the corresponding ABB mechanical interlock framework.
  • Suitable for industrial and commercial low-voltage switchgear applications.

Reliable Mechanical Circuit-Breaker Interlocking

Mechanical interlocking is used where the operating state of one circuit breaker must be physically coordinated with another. In transfer, source-selection and other interlocked switchgear arrangements, this mechanical relationship can help prevent circuit breakers from being placed into incompatible operating states.

The ABB MIR-P plate provides the breaker-specific connection required for a fixed Tmax XT4 within the ABB rear mechanical interlock system. A complete two-breaker arrangement uses the appropriate interlock frame together with a suitable MIR-P plate for each circuit breaker, allowing the mechanical interlock system to be configured for the installed breaker frames.

Typical Applications

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