How to get more inside space in enclosure while designing Din Rail Mounted products?

It is common experience that in designing a Instrumentation, automotive industry or home/building automation product such as PLC, Relays, Timers, Transducers, Transmitters, I/O circuits....or any other electrical / electronic product designer feels they should be allowed more inside space keeping the standards. Design engineers feel space crunch to accommodate all their circuits and components inside Din Rail Enclosure.

The easy solution is to have standard enclosure height as 108mm instead of 86mm keeping width same as Modular Enclosures. More height provides more inside space and occupies less rail space.

The Din Rail Enclosure Standard allows 108mm height in the enclosure which can be fitted on Din Rail fitted on panel or in junction box with display along with other MMI, MCB...

The Standard 108mm heighted Modulbox-Dualmount series is designed to provide extra space in Din Rail Enclosure.

Modulbox-Dualmount - 22.5, 70, 157 series of Modulboxes having 108mm height are standard Din Rail Enclosures are ideal for use in small, medium to large devices such as PLC. It is designed as per DIN 43880. It has cover face of 45mm high enables it to mount within large international style enclosures / distribution system with 45 mm cutouts like MCB. Modulbox offers wide designing option with three ways in PCB mounting and with customer specific solution in termination / connectors.


  • Dimensional size per DIN 43 880 - Can be mounted with Distribution system along with MCB
  • Knockout blanks for individual terminal configuration
  • Snap-together design speeds up assembly.
  • Two PCBs, Base PCB fixed on Base Plate, Vertical PCB for which cover has integral molded guides.
  • Innovative Clips design facilitates Wall / Rail Mount to Enclosures by changing its position in Base plate.
  • Terminal - standard 5mm pitch
  • Air ventilation - having slots for ventilation.
  • Protection - IP20 (finger protected) Protection against accidental contact
  • Terminals are optional - Enclosure supplied with / without terminals - customer can use standard commercial terminal available of their choice.
