Why Choose the ABB 1SDA054950R1 MIR-P Type C Mechanical Interlock Plate?
The ABB 1SDA054950R1 is a MIR-P Type C mechanical interlock plate designed for use between two compatible ABB SACE Tmax T4 and T5 moulded case circuit breakers. As part of the ABB Tmax T accessory system, it provides the mounting interface required to create a mechanical interlocking arrangement between selected breakers.
The Type C configuration is specifically intended to interlock a Tmax T4 in fixed, plug-in or withdrawable execution with a Tmax T5 630 in plug-in or withdrawable execution. When incorporated into the appropriate ABB MIR mechanical interlock assembly, it supports mechanically coordinated operation between the two circuit breakers.
Mechanical interlocking is used where two breakers must not be closed simultaneously, such as in supply changeover and source-selection systems. The MIR-P plate works with the appropriate MIR-HB horizontal or MIR-VB vertical interlock frame to form the required two-breaker mechanical interlocking system while retaining compatibility with suitable front-mounted breaker accessories.
Key Advantages
- Dedicated Type C plate for mechanical interlocking between selected Tmax T4 and T5 circuit breakers.
- Supports interlocking between T4 fixed, plug-in or withdrawable and T5 630 plug-in or withdrawable configurations.
- Helps prevent simultaneous closing of two mechanically interlocked circuit breakers.
- Suitable for source-selection and electrical changeover arrangements.
- Designed to form part of ABB's MIR mechanical interlocking system.
- Genuine ABB accessory engineered for coordinated use with SACE Tmax T circuit breakers.
Key Features
- ABB SACE Tmax T accessory.
- MIR-P Type C mechanical interlock plate.
- Designed for mechanical interlocking between two circuit breakers.
- First breaker compatibility: Tmax T4 fixed, plug-in or withdrawable.
- Second breaker compatibility: Tmax T5 630 plug-in or withdrawable.
- Used with the appropriate ABB MIR mechanical interlock frame.
- Mechanical design requires no electrical signalling contacts for the interlocking function.
- Suitable for industrial and commercial power distribution assemblies.
Mechanical Interlocking for Coordinated Power Switching
A mechanical interlock physically coordinates two circuit breakers so that operating one breaker restricts the permitted operating state of the other. This arrangement is commonly used where simultaneous connection of two power sources must be prevented independently of an electrical control system.
The ABB 1SDA054950R1 provides the Type C MIR-P mounting plate required for the specified combination of a Tmax T4 and Tmax T5 630 circuit breaker. When combined with the appropriate MIR frame assembly, it forms part of a mechanical interlocking system suitable for applications such as mains-generator, transformer and alternative-source changeover arrangements.
Typical Applications
- Mechanical interlocking between compatible ABB Tmax T4 and T5 circuit breakers.
- Mains and standby generator changeover systems.
- Alternative power-source selection assemblies.
- Transformer and incomer switching arrangements.
- Industrial switchboards and power distribution panels.
- Commercial and infrastructure electrical distribution systems.

Frequently Asked Questions
What is the ABB 1SDA054950R1?
The ABB 1SDA054950R1 is a MIR-P Type C mechanical interlock plate designed to form part of a mechanical interlocking system between selected ABB SACE Tmax T4 and T5 circuit breakers.
Which circuit breakers can be interlocked using the ABB 1SDA054950R1?
The Type C plate is specified for interlocking a Tmax T4 fixed, plug-in or withdrawable breaker with a Tmax T5 630 plug-in or withdrawable breaker.
What does the MIR-P Type C plate do?
The MIR-P Type C plate provides the mounting arrangement required for the specified pair of circuit breakers within an ABB mechanical interlocking system, helping prevent incompatible simultaneous breaker operation.
Is the ABB 1SDA054950R1 a complete mechanical interlock system?
No. The 1SDA054950R1 is the Type C interlock plate. An appropriate ABB MIR frame, such as the horizontal or vertical frame specified for the installation, is also required to form the complete mechanical interlock assembly.
Where is a Tmax mechanical interlock typically used?
Mechanical interlocks are commonly used in mains-generator, alternative-source, transformer and changeover systems where two circuit breakers must be mechanically coordinated to prevent simultaneous connection.
