• IVE unit, providing electrical interlocking and input-outputs for remote control; ensuring break-before-make, thanks to the 250 millisecond delay

Automatic Transfer Switching Equipment (ATSE)

• for class PC : 2 ComPacT NS or MasterPacT MTZ switch-disconnectors, both equipped with motor mechanism
• for class CB: 2 ComPacT NS or MasterPacT MTZ circuit-breakers, both equipped with motor mechanism
• Mechanical interlocking :
  • device for rotary handle (ComPacT NS only),
  • or keylocks with captive keys,
  • or connecting rods,
  • or cables
• IVE unit, providing electrical interlocking and input-outputs for remote control; ensuring break-before-make, thanks to the 250 millisecond delay
• Automatic controller
  • BA for utility to utility source changeover
  • UA for utility to genset source changeover, or utility to utility with advanced features
• Automatism control backplate (ACP), hosting the controller and its protections (2 miniature circuit-breakers, included). Alternatively, the controller can be set out of the backplate, using the optional 1 meter long prewired connections (or user-made connections up to 2 meters long)

ComPacT- and MasterPacT- based transfer switches enable:

• Power availability sustained during maintenance or replacement of sources (N or R), without service interruption
• Power source management optimizing power quality and power costs
• Optimized energy management by transferring the supply to another source, according to external requirements (demand/response contract, smart grid, etc.)

Quick and simple installation

• Vertical or horizontal fitting in switchboard
• Controller with convenient and DIN standardized form factor: 138 x 138 mm
• Online and offline software tools improving your efficiency:
  • Product Selector during configuration, quotation and ordering
  • EcoStruxure Power Design
  • EcoStruxure Power Build
  • EcoStruxure Power Commission

Flexibility

• leveraging the breadth of ComPacT and MasterPacT ranges, configuration enables a multiplicity of features and combinations, such as current ratings, tripping curves, breaking capacities, adjustable settings...

Reliability, dependability

• Compliant with international standards IEC 60947-6-1
• supervision enabled by integration in EcoStruxure Power digital architectures

All buildings and sites where continuity of electrical supply is critical for people, equipment or business, for instance:

• Commercial and service sector (safety systems for buildings, computer rooms for banks and insurance companies, lighting and emergency lighting systems in malls, etc.)
• Industry (assembly lines, engine rooms on ships, critical auxiliaries in thermal power stations, etc.)
• Infrastructures (port and railway installations, runway lighting systems, control systems on military sites, etc.)

An excellent choice for all standard applications, including buildings and infrastructure with the need for continuity of service and cost optimization: offices, small and medium-sized businesses
