ABB Tmax Mechanical Interlock Between Fixed Circuit Breaker (XT1-XT4)

The ABB Tmax Mechanical Interlock is designed to ensure the sequential operation of fixed circuit breakers within the XT1-XT4 series. This interlock mechanism provides a reliable method for preventing simultaneous closure of multiple circuit breakers, thus avoiding potential short circuits or overload situations. By enforcing a strict operational sequence, it enhances safety and protects electrical systems from damage. This feature is particularly valuable in applications where multiple circuit breakers are used in parallel or in series, such as distribution panels or control panels, ensuring proper coordination and preventing unintended electrical disturbances.
