ASI single level and double level miniature terminal blocks mount on 15mm DIN rail and are used in applications where space and overall size is critical.  The ASIMBK series of miniature terminal blocks carry a 300 volt rating, can handle from 30 to 12 AWG wire based on model and carry up to 50 amps.  The housings of the ASIMBK series of terminal blocks are molded from a UL94V0 material and the metal bodies and screws are a copper alloy with nickel plating to insure a reliable connection in all types of industrial applications.

The ASIMBK series of terminal blocks are equivalent to the Phoenix Contact® MBK family of terminal blocks in that they share similar design features, color, accessories and materials.  In fact, the accessories from the two are interchangeable so that you can immediately use the ASI terminal blocks as a lower-cost alternative to the Phoenix Contact® products.

The cross reference from the ASI miniature terminal blocks to the Phoenix Contact® miniature terminal blocks is as follows:


Equivalent ground circuit connection terminal blocks can be found in the ground circuit terminal block section of the ASI website.
