Why Choose the ABB 1SDA105120R1 MIR-V XT6 Rear Vertical Mechanical Interlock?
The ABB 1SDA105120R1, designated MIR-V XT6 MECH LOCK REAR VE. 2 C.BREAKE, is a genuine ABB rear vertical mechanical interlock designed for two SACE Tmax XT6 circuit breakers. It provides a mechanical interlocking arrangement between the two breakers, preventing incompatible simultaneous operating states in applications where coordinated switching is required.
ABB specifies the accessory as a mechanical interlock, rear vertical, between two XT6 circuit breakers. The vertical configuration makes it suitable for switchboard layouts where the two associated breakers are installed one above the other, with the interlocking mechanism positioned at the rear of the circuit breakers.
Designed specifically for the ABB SACE Tmax XT6 platform, the 1SDA105120R1 forms part of ABB's mechanical interlocking accessory system. The interlock has a net weight of approximately 2.7 kg and is used with the appropriate ABB MIR-P mounting plates for the circuit breakers being interlocked.

Mechanical Interlocking for Vertically Arranged XT6 Circuit Breakers
Mechanical circuit-breaker interlocks are used where the operating states of two breakers must be physically coordinated. Rather than relying solely on electrical control logic, the interlocking mechanism mechanically restricts incompatible breaker operation, making it useful in applications such as source changeover, supply selection and other controlled switching arrangements.
The ABB 1SDA105120R1 is specifically configured for two vertically arranged SACE Tmax XT6 circuit breakers, with the interlocking mechanism located at the rear. For a complete XT6 rear interlocking set, the MIR-V mechanism is combined with the appropriate MIR-P plate for each circuit breaker, allowing the system to be integrated into the intended switchgear configuration.
Typical Applications
- ABB SACE Tmax XT6 circuit-breaker installations.
- Vertically arranged pairs of XT6 circuit breakers.
- Mechanical source-selection and changeover arrangements.
- Industrial low-voltage switchboards.
- Power distribution and protection systems.
- Installations requiring mechanically coordinated operation of two circuit breakers.
