1SDA105117R1 ABB MIR-H XT5 Rear Horizontal Mechanical Interlock for 2 Circuit Breakers

Why Choose the ABB 1SDA105117R1 MIR-H XT5 Rear Horizontal Mechanical Interlock?

The ABB 1SDA105117R1 is a rear horizontal mechanical interlock designed for installations involving two ABB SACE Tmax XT5 moulded case circuit breakers. Identified as MIR-H XT5 MECH,LOCK REAR HO. 2 C.BREAKER, this genuine ABB mechanical accessory provides a physical interlocking arrangement between two breakers in low-voltage power distribution systems.

As part of the ABB SACE Tmax XT mechanical accessory range, the MIR-H arrangement is used where the operating states of two circuit breakers must be mechanically coordinated. The interlock acts at the rear of the breakers and is configured for a horizontal two-breaker arrangement, making it suitable for switchboards and switching systems where simultaneous operation must be mechanically restricted.

The 1SDA105117R1 is specifically associated with the XT5 frame and can form part of mechanical interlocking arrangements involving fixed, plug-in or withdrawable Tmax XT configurations when the appropriate mounting plates and associated components are selected. This provides panel builders with a dedicated ABB solution for mechanically coordinated switching applications.

Reliable Mechanical Interlocking for Two Tmax XT5 Circuit Breakers

Mechanical interlocks are used where two circuit breakers form part of a coordinated switching arrangement and their operating states must be physically linked. The mechanism provides direct mechanical interlocking rather than relying solely on electrical control logic, supporting dependable switching arrangements in power distribution and transfer applications.

The ABB 1SDA105117R1 provides the rear horizontal interlocking mechanism for two compatible Tmax XT5 circuit breakers. Appropriate MIR-P mounting plates are selected according to the breaker mounting configuration, enabling the interlock to be incorporated into fixed, plug-in or withdrawable installations where supported by the Tmax XT system.

Typical Applications

• Mechanical interlocking of two ABB SACE Tmax XT5 circuit breakers.
• Industrial low-voltage switchboards.
• Power distribution and switching assemblies.
• Source-changeover and transfer switching arrangements.
• Commercial and industrial electrical distribution systems.
• Panel-building applications requiring coordinated breaker operation.
