The mechanical interlocks offer multiple solutions for installation that simplify their integration into the switchgear. The interlocks can be mounted: • vertically VR • horizontally HR • mixed L Different types of interlocks can be supplied ac- cording to the maximum distance between two in- terlocked breakers:

The ATS021 and ATS022 devices can also be used with all automatic circuit-breakers and switch-dis- connectors of the Tmax XT family. The ATS021 and ATS022 devices have been designed to be self-pow- ered. ATS022 is also designed for the connection of an auxiliary supply, which enables the use of further functions. The ATS021 and ATS022 devices carry out control of both power supply lines and also analyze: • phase imbalance; • frequency imbalance; • phase loss. In addition to the standard control functions, the ATS022 unit also permits: • the priority line to be selected; • a third circuit-breaker to be controlled; • the device to be integrated into a supervision sys- tem with Modbus communication (auxiliary sup - ply needed); • parameters to be read and set, and measure- ments and alarms to be displayed by means of a graphical display. Typical applications are: supply of UPS (Uninter - rupted Power Supply) units, operating rooms and primary hospital services, emergency power for civil buildings, airports, hotels, databases and tele- communication systems and power supply of in- dustrial lines in continuous processes. For correct configuration, each circuit-breaker con- nected to the ATS021 or ATS022 device must be fit- ted with the following accessories: • mechanical interlock; • motorized control of opening and closing; • contact for signalling status (open / closed) and contact for signalling tripping; • contact for signalling circuit-breaker racked in (for withdrawable circuit-breaker).

For B, C and D types, the maximum distance be- tween the two furthest breakers is 3200mm for horizontal configurations and 2000mm for vertical configurations. It is possible to make the mechani- cal interlock among three circuit-breakers disposed in 'L position' by using the cables of three horizon- tal circuit-breakers interlock. The distance between the horizontal and vertical circuit- breakers must mantain the minimum and maximum distance. All cables can be cut to provide easy installation in switchboards. Mechanical interlocks are not compatible with AUX 15Q, the lock for preventing door opening when the circuit breaker is in the closed position (DLC) or when the circuit breaker is in the racked in or test position (DLP). if mounted on the right side. External Automatic Transfer Switches ATS The ATS (Automatic Transfer Switch) is a net - work-unit transfer device used in installations where switching from the main power line to an emergency line is required in order to ensure that power is supplied to the loads in the case of power loss or abnormalities from the main line. These de- vices are able to control the entire transfer proce- dure automatically, but also offer commands for performing the procedure manually. The new generation of ATSs (ATS021 and ATS022) offers the most advanced and complete solution for ensuring service continuity.
