The mechanical interlocks offer multiple solutions for installation that simplify their integration into the switchgear. The interlocks can be mounted: • vertically VR • horizontally HR Maximum distance between two interlocked XT7 breakers is 2750mm in the horizontal configuration and 1000mm in the vertical one. Mechanical interlocks are not compatible with AUX 15Q and the lock for preventing door opening when the circuit-breaker is in the closed position (DLC) and mounted on the right side.
