Air Circuit Breakers & Associated Parts

If you need a parts solution we are here to help!  There are factors that affect parts availability for your equipment due to vintage and availability from the Manufacturers – whatever you need for your ACB give us a call.

New Parts

We can advise, source and deliver parts to suit your equipment.  This may be in the event of a breakdown or contingency for your site; avoiding sometimes costly lead-times.

Sanskriti Engineering are distributors of Mitsubishi equipment and can offer excellent procurement time for these parts.

We also hold new items for various current and older breakers in stock.  We aim to carry in stock, and to site, key parts that we have experience of failures with for main manufacturers; ABB, Merlin Gerin/ Schneider, GE.

We also are Suppliers and Approved Installers for Satin American Q-Series trip units.  We stock these units to provide rapid support for replacing faulty trip units on obsolete breakers.

Second Hand or New Old Stock Parts

From complete ACBs to a single spring – we have comprehensive stock of various parts to help resolve a situation or keep an older piece of equipment operating, this can be the difference between spending a small amount on a single component to fix your existing obsolete ACB and spending a large amount on an otherwise unavoidable upgrade to a new model.


An example of some Mitsubishi AE-S auxiliary switches, control PCB and coils. These are available from Sanskriti Engineering in various voltages depending on your application. Being able to replace even one of these obsolete components could be the difference between 30 minutes downtime on an existing ACB, and potentially days of downtime and necessity for a complete breaker change!!

Sanskriti Engineering carry a substantial stock of Mitsubishi AE-SS parts. Examples shown above are a charging motor, drawout mechanism and shunt tripping coil.
