1SDA054953R1 ABB MIR-P Type F T5-T5 Mechanical Interlock

Why Choose the ABB 1SDA054953R1 MIR-P Type F Mechanical Interlock?

The ABB 1SDA054953R1 is a MIR-P Type F mechanical interlock designed for compatible ABB SACE Tmax T5 moulded case circuit breakers. Identified as MIR-P tipo F (T5-T5), this genuine ABB accessory provides mechanical coordination between two T5 circuit breakers where their operating states must be interlocked.

Mechanical interlocking is used in power-distribution systems where two circuit breakers must follow a defined operating relationship and incompatible simultaneous states need to be prevented. The MIR-P achieves this through a mechanical arrangement rather than relying solely on electrical control logic, making it suitable for source-selection, transfer and other interlocked switching applications.

The 1SDA054953R1 is the Type F configuration for a T5-T5 breaker combination. Its dedicated ABB design provides compatibility with the corresponding Tmax T5 equipment and supports professional implementation of mechanically interlocked low-voltage distribution systems.

Type F Mechanical Interlocking for Tmax T5-T5 Arrangements

A mechanical interlock establishes a physical relationship between circuit breaker operating mechanisms so that the breakers follow the required switching constraints. This is particularly valuable in installations involving alternative power sources or distribution paths where certain combinations of breaker states must be mechanically prevented.

The ABB 1SDA054953R1 provides the Type F MIR-P configuration for two compatible Tmax T5 circuit breakers. Its mechanical operating principle makes it a useful component for industrial source-selection and power-transfer systems requiring dependable coordination between the associated breakers.

Typical Applications

• Interlocking two ABB Tmax T5 circuit breakers.
• Main and standby power-source arrangements.
• Source-selection switchboards.
• Power-transfer systems.
• Industrial low-voltage distribution installations.
• Switchboards requiring mechanically coordinated breaker operation.
