ABB 1SDA105120R1 Mechanical Interlock Circuit Breakers

Description

• The ABB 1SDA105120R1 is a mechanical interlock designed for rear vertical mounting between two ABB XT6 series circuit breakers. This interlock mechanism is used to ensure that only one of the connected circuit breakers can be in the "ON" position at a given time. It prevents both circuit breakers from being in the "ON" position simultaneously, which can help enhance safety and avoid unintended electrical configurations.

• Mechanical interlocks are commonly used in electrical panels and distribution systems to establish proper sequencing and prevent potentially hazardous situations, such as parallel switching of multiple sources. In the case of the ABB XT6 series circuit breakers, this interlock is specifically designed to fit and function with these breakers when mounted in a rear vertical orientation.

• This interlock, you can achieve a reliable and mechanically enforced method of controlling the state of two circuit breakers to ensure that they operate in a coordinated and safe manner.
